Question

What is the surface area of the rectangular prism shown below?
​

Answer 1

Answer: 238 ft ^ 2.

Explanation:

To find surface area of a rectangular prism, use this formula:

`SA=2(l*w+w*h+h*l)`

To find the area of a normal rectangle, you would multiply the length by the width, so for the surface area of a rectangular prism, you're just finding the areas of the sides and adding them together.

Substituting 5 for h, 3 for w, and 13 for l, you can solve:

`SA = 2(13*3+3*5+5*13)\\SA = 2(39+15+65)\\\\SA = 2(119)\\\\SA = 238`
