Q5 of 32 Page 115

Volume of a cuboid is 34.50 cubic metre. Breadth and height of the cuboid is 1.5m and 1.15m respectively. Find its length.

Given: Volume of cuboid (V) = 34.50 m3

Breadth of cuboid (b) = 1.5 m


Height of cuboid (h) = 1.15 m


Volume of a cuboid is given by,


Volume = length × breadth × height


⇒ V = lbh


⇒ l = V/bh


⇒ l =


⇒ l = 20


Thus, length of cuboid is 20 m.
