To find the surface area of a rectangular prism, you need to calculate the area of each face and then add them together.
The formula for surface area of a rectangular prism is:
2lw + 2lh + 2wh
Given:
Length (l) = 12 inches
Width (w) = 5 inches
Height (h) = 3 inches
Plugging the values into the formula:
2(12)(5) + 2(12)(3) + 2(5)(3)
= 2(60) + 2(36) + 2(15)
= 120 + 72 + 30
= 222
Therefore, the surface area of the rectangular prism is 222 square inches.
