To find the surface area of a rectangular prism, you need to calculate the area of each face and then add them all together.
The formula to calculate the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Given:
Length (l) = 12 inches
Width (w) = 5 inches
Height (h) = 3 inches
Plugging the values into the formula:
Surface Area = 2(12)(5) + 2(12)(3) + 2(5)(3)
Surface Area = 120 + 72 + 30
Surface Area = 222 square inches
Therefore, the correct answer is 222 square inches.
