The surface area of a rectangular prism can be calculated using the formula 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
Surface area = 2(10)(9) + 2(10)(3) + 2(9)(3)
Surface area = 180 + 60 + 54
Surface area = 294 square inches
Therefore, the surface area of the rectangular prism is 294 square inches.
