Here is Elena’s work for finding the surface area of a rectangular prism that is 1 foot by 1 foot by 2 feet. She concluded that the surface area of the prism is 296 square feet. Do you agree with her conclusion? Explain your reasoning.
Disagree, Elena calculated the area of the top and bottom faces in square inches but the area of the side faces in square feet. The combined area of the top and bottom faces is 2 square feet, so the correct surface area is 10 square feet.
