Surface area of a rectangular prism is calculated by finding the area of all six faces and adding them together.
In this case, there are 2 faces with dimensions 10x9 inches (top and bottom), 2 faces with dimensions 10x3 inches (front and back), and 2 faces with dimensions 9x3 inches (left and right).
The surface area can be calculated as follows:
Surface area = 2(10x9) + 2(10x3) + 2(9x3)
Surface area = 180 + 60 + 54
Surface area = 294 square inches
Therefore, the surface area of the rectangular prism is 294 square inches.
Use the image to answer the question.
An illustration shows a rectangular prism with length 10 inches, width 9 inches, and height 3 inches. The top, front, and right faces are visible. The edges that are not visible are represented by dashed lines.
