If the lateral surface area of a prism is 240 cm2 and height is 8 cm, what is the perimeter of the base?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 30 cm.
Lateral surface area of a prism = Perimeter of base × Height
LSA = 240 cm2, Height = 8 cm
So,
Perimeter × 8 = 240
Perimeter = 240/8 = 30 cm
