Calculate the surface area of a prism with the following dimensions.The length (l) = 7 units, the width (w) = 2 units and the height (h) = 6 units:

For a rectangular prism, surface area is 2(lw + lh + wh). Substituting the dimensions gives 2[(7 × 2) + (7 × 6) + (2 × 6)] = 2(14 + 42 + 12) = 136 square units. The correct choice is 136 sq. units.
