Question

The area of the front face of a rectangular prism is 12 cm2. The area of the top face is 16 cm2, and the area of the right side face is 20 cm2. What is the surface area of the rectangular prism?

56 cm2
48 cm2
60 cm2
96 cm2

Answer 1

actually it's 96 cm2      not cm 3

Answer 2

Correct answer is 96 $cm^{2}$.

Surface area of rectangular prism:

A rectangular prism has 6 rectangular faces.

To find the surface area of a rectangular prism, add the areas of all 6 faces.

As the surface area of top face is same as bottom face and right face is same as left face and top face is same as bottom face. So,  

=> Surface Area of a rectangular prism = 2*(surface area of top face + surface area of right side face and surface area of front face)

=> 2*(12$cm^{2}$ + 16$cm^{2}$ + 20$cm^{2}$ )

=> 2*(48$cm^{2}$ )

=> 96 $cm^{2}$.
