Question

The perimeter of the base of a cuboid is 14 cm. It's lateral surface area is 231 cm^2. Find it's height.

Answer 1

We know that faces of cuboid is in the shape of rectangle .
The perimeter of base of cuboid = 14 cm
=> 2 ( l + b ) = 14 cm
Lateral surface area = 231 cm^2
=> 2 ( l+ b) h = 231 cm^2
=> 14 h = 231cm^2
=> h = 231 / 14
=> h = 33 / 2
=> h = 16.5 cm
