The length, breadth and height of a cuboid are 15 m, 6 m and 5 dm respectively. The lateral surface area of the cuboid is
Given: Length = 15 m
Breadth = 6 m
Height = 5 m
Lateral surface area of a cuboid = 2(Length +Breadth) × Height
1 m = 10dm
⇒ 5dm =0.5m
Lateral surface area = 2(15+6) × 0.5 m2 = 1× 21 m2
= 21 m2
