Question

A rectangular prism has a base perimeter of 28 m and height 12 m. What is its lateral surface area?

• A. $316m^2$
• B. $346m^2$
• C. $336m^2$
• D. $326m^2$

Answer 1

The correct option is C

$336m^2$

Let perimeter of the base = P and height =H.

Lateral surface area of a Prism = perimeter of the base $\times$ height

$\therefore$ Lateral surface area of the Prism $=P\times H$
$=28\times 12$
$=336m^2$
