Explain the total surface area of a rectangular prism with a base of 2.8 in a length of 7.1 in and a height of 3.2 in
1 answer
The total surface area of a rectangular prism with a base of 2.8 in, a length of 7.1 in, and a height of 3.2 in is equal to the sum of the areas of all six faces. The area of each face can be calculated by multiplying the length and width of the face. The two faces with the base of 2.8 in and the length of 7.1 in have an area of 19.48 in2. The two faces with the base of 2.8 in and the height of 3.2 in have an area of 8.96 in2. The two faces with the length of 7.1 in and the height of 3.2 in have an area of 22.72 in2. Therefore, the total surface area of the rectangular prism is 19.48 + 8.96 + 22.72 = 51.16 in2.
