    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...  moreWhy 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 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

    Noorjahan Binte Farhana There is given Small and tall giraffe height. And the tall giraffe volume is 5400 meter queb. volume= length × width × height.
    consume the length X and width Y for tall and small giraffe
    so, for tall giraffe...  moreThere is given Small and tall giraffe height. And the tall giraffe volume is 5400 meter queb. volume= length × width × height.
    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

    Jesmin Akhter given,
    Bigger giraff height = 6m
    And the volume of bigger giraff = 5400m^3
    we know a formula...  moregiven,
    Bigger giraff height = 6m
    And the volume of bigger giraff = 5400m^3
    we know a formula that,
    volume = lenght * wide * hight
    let, lenght = a, wide = b
    so, volume = lenght * wide * hight
    => 5400m^3 = a * b * 6m
    => ab = 5400m^3 / 6m
    => ab = 900m^2 ...........(i)
    given, Smaller giraff hight = 4m
    know we have to be findout the volume of smaller giraff.
    let, volume of smaller giraff = x
    leangth = a
    wide = b
    we know,
    valume = length * wide * hight
    => x = ab * 4m
    => x = 900m^2 * 4m [ puting the value of a and b from equation...    less

    Nur E ferdus Monika matin At first, it is mentioned that both giraffes are similar. That means the ratio of height, length,
    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,...  moreAt first, it is mentioned that both giraffes are similar. That means the ratio of height, length,
    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
