Question

A cuboid is 12 cm long, 8 cm wide, and 5 cm high. Find its volume and total surface area.

Solution

1. Volume = l x b x h = 12 x 8 x 5 = 480 cm^3.
2. Total surface area = 2(lb + bh + lh) = 2(12 x 8 + 8 x 5 + 12 x 5).
3. = 2(96 + 40 + 60) = 2 x 196 = 392 cm^2.
4. The volume is 480 cm^3 and the total surface area is 392 cm^2.
