In order to find the total surface area of the rectangular prism, we need to calculate the area of each of the six faces and then add them all together.
The measurements of the rectangular prism are:
Length = 20 inches
Width = 16 inches
Height = 12 inches
Calculating the area of each face:
1. Front Face: 20 inches x 12 inches = 240 square inches
2. Back Face: 20 inches x 12 inches = 240 square inches
3. Top Face: 20 inches x 16 inches = 320 square inches
4. Bottom Face: 20 inches x 16 inches = 320 square inches
5. Left Side Face: 16 inches x 12 inches = 192 square inches
6. Right Side Face: 16 inches x 12 inches = 192 square inches
Adding all the areas together:
240 + 240 + 320 + 320 + 192 + 192 = 1404 square inches
Therefore, the total surface area of the rectangular prism that will be covered by wrapping paper is 1408 inches squared.
So, the correct answer is:
C) 1408 inches squared
