Question

What is the surface area of a rectangular prism with dimensions 3 units high, 2 units wide, and 5 units long? (in square units)

A) 20
B) 30
C) 40
D) 50

Answer 1

The surface area of a rectangular prism is found by adding up the area of each face, using the formula 2lw + 2lh + 2wh.

Step-by-step explanation:

To find the surface area of a rectangular prism, we need to find the area of each face and then add them up. The formula for the surface area of a rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

Given the dimensions of the rectangular prism are 3 units high, 2 units wide, and 5 units long, we can substitute these values into the formula:

Surface Area = 2(2)(3) + 2(2)(5) + 2(3)(5) = 12 + 20 + 30 = 62 square units

Therefore, the surface area of the rectangular prism is 62 square units.
