Question

A cuboid is 25 cm long, 15 cm broad, and 8 cm high . How much of its volume will differ from that of a cube with the edge of 16 cm?

Answer 1

Volume of a cuboid (V₁) of measures

= 25 cm, b = 15 cm, h = 8 cm.

V₁ = 25 × 15 × 8 = 3000 cm³

Volume of a cube of measure side (s) = 16 cm is

V₂ = (s)³ 

= (16)³ = 16 × 16 × 16

= 4096 cm³

The difference between their volumes

= V₂ – V₁

= 4096 – 3000

= 1096 cm³
