    This method will work when all the sides are of the same length. Then, we can find the volume of a cube just knowing the measurement of only one side. If a cube has side length "x" then Volume = x × x × x a which results in the formula, Volume = x³. This is where we get the term called"cubed". When we use power to the 3 over something, we call it cubed. When units of Measure are calculated, we find the volume of an object, and the units are cubed. This means that if the measurements of the sides are in miters, then the answer will be in cubed miters.  less

    In question, it represents the subject of ‘similarity statistics’. This means that the ratio of height, length, and width will be the same.
    In the equation, we are seeing that the dimension of both the values are different which needs to be equal. Over here, the height is a one-dimensional unit(meter) but the volume is three-dimensional (meter^3). So, we need to cube it to make it evenly dimensional.
    ''Why would it work?''
    Otherwise, it is not according to the rules and the answer will be wrong.
    So, given,
    Height of small giraff= 4m
    = 4 x 4 x4 = 216m^3
    Height of big giraff= 6m
    = 6x 6 x6 = 64 m^3
    Volume of big giraff= 5400m^3
    and, let the volume of small giraffe be 'x' m^3.
    Now. we know,
    the formula of similarity,
    Height of big giraffe/Height of small giraffe=Volume of big giraffe/Volume of small giraff.
    ==> 216/64 = 5400/ 'x'
    ==>216x =345600
    ==> x =1600
    Therefore, the volume of the small giraff is 1600 m^3.  less

    consume the length X and width Y for tall and small giraffe
    so, for tall giraffe X*Y*6=5400
    XY=5400/6
    XY= 900
    Now, for small giraffe volume X*Y*4
    900*4=3600 [ we have find out XY=900]
    The tall giraffe is 1.5 tall more than small giraffe.
    as, 3600*1.5=5400

    width, and the dimension of each part will be the same for the two Giraffe. The volume of a
    three dimensional figure is- volume= length X width X height so, Volume(Small)/Volume
    (Large)=Length(s)×width(s)×Height(s)/Length×width×Height
    Height(s)/Height=4/6=2/3 So, Length(s)/ Length=2/3 and width(s)/width=2/3
    Volume(Small)/Volume (Large)= (2/3) ×(2/3)×(2/3) Volume(Small)= (8/27)× Volume (Large)
    = (8/27) × 5400 m^3 = 1600 m^3 This formula will work because If we calculate volume part
    by part and make a sum to get the total volume of the small giraffe as it is irregular-shaped,
    it will remain unchanged because each part maintains the same ratio of 2/3 with the large
    Giraffe as both are similar.  less

    Mujtaba Rafid Let's clear the math first(just for the sake of it)-
    Housing cost- BDT 10,000
    Total cost of employees- BDT 10,000

    Housing cost- BDT 10,000
    Total cost of employees- BDT 10,000
    Total fixed cost- 10,000 + 10,000= 20,000 taka
    Sales price per unit- BDT 500
    Variable cost per unit- BDT 250
    Sales price per unit - Variable cost per unit= BDT 250
    So the break-even point= 20,000/250= 80
    So basically, Mithy needs to sell 80 cupcakes per month to make sure that the cost and total revenue are equal.
    So what can she do to increase her sales?
    A tricky question that does not have a straightforward answer because it includes so many variables.
    All we can do is to lay out some tips.
    Since the cupcakes are amazing, she can take a bit of risk. She can invest more money and spend more money on marketing. For example, she can use it to boost her Facebook business page to get more traction or hire a part-time online marketer who will keep a close eye on her customers and see what they want. It will be risky because the break-even point will be higher which means she must sell more...    less

This four letter word isn’t a comfortable thing in someone's life. You have to go through a series of depressions, complications and sleepless nights if this term ever get connected with you. Well, like everyone else, I also have many situations in my life where I considered myself as a complete loser.You know being an introvert makes you disconnected from social life and it's not a joke. Being like that I was ditached from every success I could have achieved earlier. I was a shy person who could not even order a food for herself in any restaurant. I was someone who used to know the answers of most of the questions in school but always hesitated to talk. But you can not be like this forever right? In this century if you want to be successful, you have to talk and discuss. You have to share your opinions so that other persons can know your value. My university clubs did a great job to pull out the talents of me. They forced me to talk everyday and...    less

After 3months of continuous practice, I was selected as an anchor of our varsity convocation program. A girl who could not even talk became an anchor? Yes that is right. I had my will to change the awkwardness inside me and I succeed. If you want something truly, you will achieve that no matter what. Just have patience. You will surely be a winner of that once you thought would be your loosing point.

People used to say I am unable to make others understand my thoughts. I was Bullied for it. Last year I felt depressed but didn't find anyone to share my pain. So I expressed my thoughts and pain in words on my facebook timeline. Alhamdulillah, Not only it cures my heavy heart but also friends start liking my writings and give compliments. Then one day, a friend asked me to do an internship as a content writer. I had no idea about it. I googled, learned, did low paid writing jobs, sent CVs, gave interviews and got rejected many times. Every time I fail I learn something new from my mistakes. Before the year ends, alhamdulillah, I have 2 paid freelancing writing works, one internship. Even i won a physics quiz of coolinventors though I have been a business student from the very beginning. I have many 'loser to successful' stories, but 'how an introvert girl becomes successful in sharing her thoughts' is...    less

The boys were about to give up and almost lost hope. But they stood together and today their fight has led to a worldwide reputation as one of the best and most well-known K-pop bands in the world.
    Taehyung was a son of a farmer; RM's mom used to pressure him about his studies, career; Suga, who loved music but his family always burnt all his hard work as they wanted him to focus on his studies.
    The band has almost spread out because they don’t have enough money to continue, no funds, so a few members had to choose between food and transportation and do two things. Behind their confident presence, they were constantly battling self-doubt and frustration. In fact, there is a difference even if everyone loses. "The real losers in life are not those who try and fail, but those who fail to try."  less

This project gives shelter to homeless people, those people were barely surviving before they got a house from this project. Now they can stay focus on their daily livelihood. The project has been going economic vulnerability of many homeless families by providing them with shelters and necessary financial assistance to rebuild their life. As the project now targets the impoverished people of the whole country, by aiding them to build their shelter with a means of income generation can also check the displacement of people from one place to another. Beside that this project provided necessary training to them and revolving interest-free micro-credit to enhance income generating activities to improve their livelihoods and make them self-reliant. With this they can start a small business or cultivate their own food and keeping household pet. This project surely a blessing to those people like Rahim Miah.  less

Homeless women, teenagers, and children feel helpless or unprotected due to multiple forms of victimization, including forced, coerced, or manipulated sexual activity. So, ''The Asrayan project'' is a development project which aims at providing homes for the homeless and gradually making them self-dependent to contribute to the national economy. This project will help lower-income group people to some extent but government support is needed to achieve this to the fullest, such as,
    
    1.Setting priority for ensuring to access good jobs for lower-income group people.
    
    2.Providing Microloans can be beneficial to the landless people who want to start a new business. If the business increases, it will also create more employment opportunities for others.  less
