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 cu. meters. Find the breadth of the wall.
A. 30 cm
B. 40 cm
C. 50 cm
D. 55 cm
Let the breadth of the wall be x meters.Then, Height = 5x meters and Length = 40x meters.
x * 5x * 40x = 12.8 x3=12.8/200 = 128/2000 = 64/1000
So, x = (4/10) m =((4/10)*100)cm = 40 cm
