Question

the volume of a wall ,5 times as high as it is broad and 8 times as long as it is high,is 12.8 metre cube find the breadth of wall

Answer 1

Let the breadth of the wall be x metres.

Then, Height = 5x metres and Length = 40x metres.

      x * 5x * 40x = 12.8

=> x^3 = 12.8/200 

=> x=  0.4m = 40cm
