The surface area of a rectangular prism can be found by adding up the areas of all its faces.
In this case, the top and bottom faces have an area of length times width:
2 * (12 * 5) = 120 square inches
The front and back faces have an area of height times width:
2 * (3 * 5) = 30 square inches
The right and left faces have an area of length times height:
2 * (12 * 3) = 72 square inches
Adding up all the areas:
120 + 30 + 72 = 222 square inches
Therefore, the surface area of the rectangular prism is 222 square inches.
Use the image to answer the question.
An illustration shows a rectangular prism with length 12 inches, width 5 inches, and height 3 inches. The top, front, and right faces are visible. The edges that are not visible are represented by dashed lines.
Solve for the surface area of the rectangular prism.
