The surface area of a rectangular prism is calculated by finding the area of each individual face and then adding them all together.
The formula for the surface area of a rectangular prism is:
Surface Area = 2lw + 2lh + 2wh
Plugging in the given dimensions:
Surface Area = 2(12*5) + 2(12*3) + 2(5*3)
Surface Area = 2(60) + 2(36) + 2(15)
Surface Area = 120 + 72 + 30
Surface Area = 222 square inches
Therefore, the correct answer is:
222 square inches
