Answer 1

Given :

The dimensions of cuboid are 4 x 5 x 8 in cm

To find :

Find its total surface area.

Solution :

Dimensions of a cuboid = 4 cm x 5 cm x 8 cm

So, I = 4 cm, b = 5 cm and h = 8 cm.

Hence, total surface area of cuboid

➸ 2 (l x b + b x h + l x h)

➸ 2 (4 x 5 + 5 x 8 + 4 x 8) cm²

➸ 2x (20 + 40 + 32) cm²

➸ 2 x 92 cm²

➸ 184 cm²
