Question

Use the image to answer the question.

A rectangular prism net has a length of 6 inches, width of 3 inches, and a height of 2 inches.

Use the net to find the surface area of this rectangular prism.

A.
36 square cm

B.
72 square cm

C.
66 square cm

D.
60 square cm

Answer 1

To find the surface area of the rectangular prism, we need to add up the areas of all six faces.

From the net, we can see that there are two rectangles with dimensions 6 x 3 (the top and bottom faces), two rectangles with dimensions 2 x 3 (the left and right faces), and two rectangles with dimensions 6 x 2 (the front and back faces).

The area of each rectangle is given by the formula A = lw, where l is the length and w is the width.

So, the surface area of the rectangular prism is:

2(6 x 3) + 2(2 x 3) + 2(6 x 2)

= 2(18) + 2(6) + 2(12)

= 36 + 12 + 24

= 72

Therefore, the surface area of the rectangular prism is 72 square inches.
