A rectangular prism measures 8 inches in width, 12 inches in length, and 4 inches in height. What is the surface area of the prism? Enter your answer in the box.
To find the surface area of the rectangular prism, we need to calculate the area of each of the six sides and then add them up.
The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
where l = length, w = width, and h = height.
Plugging in the given values:
Surface Area = 2(12)(8) + 2(12)(4) + 2(8)(4)
Surface Area = 192 + 96 + 64
Surface Area = 352 square inches
Therefore, the surface area of the prism is 352 square inches.
