2. Find the surface area of the prism.

Answer 1

In order to find the surface area of a prism, you need to add the area of all of its sides. The formula for the surface area of a rectangular prism is:

SA = 2( lw + lh + wh), where l is the length, w is the width, and h is the height.

Here's an example: Let's say we have a rectangular prism with the length of 5 cm, width of 4 cm, and height of 3 cm.

Then the surface area of this prism would be:

SA = 2(5 x 4 + 5 x 3 + 4 x 3)
SA = 2(20 + 15 + 12)
SA = 2(47)
SA = 94

So the surface area of the prism is 94 square centimeters.
