# The volume of a w

Given: The volume of a wall is 12.8 m3.

Height is 5 times the breadth and Length is 8 times the height.

Height = 5x

Length = 8 × (5x) = 40x

Volume of a Cuboid is given by: l × b × h (here l, b, h are, length, breadth, height respectively)

l × b × h = 12.8

x × 5x × 40x = 12.8

200x3 = 12.8

x3 = m3 =

x= m = m = 0.4 m

x = 0.4m = 0.4 × 100 = 40cm
