1 foot
2 feet
A package is shaped like a right rectangular prism. Use the dimensions shown to find the surface area of this package.

A)6 square feet
B)12 square feet
C)20 square feet
D)22 square feet

Answer 1

The surface area is 22 square feet

Explanation:

For a right rectangular prism, we have the formula for the area as;

A = 2(lb + lh + bh)

Accordingly, we have l as the length, b as the breadth and h as the height

Using the given dimensions, we have

A = 2(3(1) + 3(2) + 1(2))

A = 2(3 + 6 + 2)

A = 2(11) = 22 square feet
