Final answer:

The surface area of a right rectangular prism can be found using the formula: Surface Area = 2lw + 2lh + 2wh. For a prism with length 6 inches, width 4 inches, and height 7 inches, the surface area is 144 square inches.

Step-by-step explanation:

The surface area of a right rectangular prism can be found using the formula:

Surface Area = 2lw + 2lh + 2wh

Where l is the length, w is the width, and h is the height of the prism.

For example, if the length is 6 inches, the width is 4 inches, and the height is 7 inches, the surface area is:

Surface Area = 2(6)(4) + 2(6)(7) + 2(4)(7) = 144 square inches
