    • Nirjona Akter
      Zarin sadaf snigdha Since both the Giraffes are similar & we know the volume & heigh of larger Giraffe & the height of the smaller Giraffe we can use Similarity to find the volume of smaller Giraffe.

      Shadman Chowdhury The volume of the smaller giraffe will be found by different methods. If the first approach doesn't work, try another method.

      The formula for calculating volume is: V=L*W*H where L is length, W is width and H is height. As you can see in the diagram...  more

    • Nirjona Akter
      Shadman Chowdhury The first method is to calculate the ratio of the surface area of a smaller giraffe compared to that of the larger one and then multiply this number with the volume of a larger giraffe. This will give us an approximate answer for the volume of the...  more

      Zakaria Ahomed First of all the main thing comes here is about similarity. But a difference in case of height and dimensions. So in this case we can do following things.
      Suppose,the volume of smaller one = x
      Ratio of their Heights => 4/6= 2/3
      Again,if we cube...  more
    • Nirjona Akter
      Zakaria Ahomed That's because If two solids are similar, the ratio of their volumes is equal to the cube of the ratio of their corresponding sides.The cube came 8/27. And the rest of the things are as given. The equation will be (common ratio)^3=ratio of volumes. Thus...  more

      Kanta Akter We can just simply do this calculation as the Giraffes are similar. the bigger one is 4/6 times the smaller one in all three dimensions that result in a smaller one 5400×4/6×4/6×4/6 or 5400×(4³/6³)=1600m³

      Then why this will...  more

    • Nirjona Akter
      Nirjona Akter In the passage, it is stated that giraffes are similar with different sizes. We can calculate the volume of a smaller giraffe by using given values along with simple math calculation. So If the height of 6 makes a 5400 m³, then the first part of the...  more

    • Nirjona Akter
      Nirjona Akter Why this formula will work?

      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...  more

      Shaikh Nafisa Binte Fahad ''How will it work?''
      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...  more
