Determine the surface area of a rectangular prism with the following dimensions:Length = 2 cm; Width = 1 cm; Height = 3

For a rectangular prism, surface area is 2(lw + lh + wh). Using length 2 cm, width 1 cm, and height 3 cm gives 2[(2 × 1) + (2 × 3) + (1 × 3)] = 2(11) = 22 square centimeters. The correct choice is 22 sq. cm.
