Question

A rectangular prism is 4 meters long, 5 meters wide, and has a height of 7 meters. What is its surface area?

1.140 m2
2.166 m2
3.84 m2
4.70 m2

Answer 1

The surface area is all the areas of all the exterior faces in a 3D shape.

Doing all the possibilities, 4 * 5 * 2 , 5 * 7 * 2, 4 * 7 * 2 = total surface area
40 + 70 + 56 = 166 m^2

The answer is 2. 166 m^2
