Use the net to compute the surface area of the three-dimensional figure. a) 210 units2 b) 225 units2 c) 240 units2 d) 280 units2

To find the surface area of this rectangular prism, you need to find the area of all six faces. The front and back faces have an area of square unit(8x5) each totaling 80 square units. The side faces have an area of 25 square units(5x5) each totaling 50 square units and the top and bottom of the rectangular prism have areas of 40 square units each totaling 80 square units. Adding all these together (80 + 80 + 50) gives us the total surface area of 210 square units.
