What are the steps to finding the total surface area of a rectangular prism with a width of 2.8 a length of 7.1 and a height of 3.2
1. Calculate the area of the two rectangular faces:
A = 2.8 x 3.2 = 8.96
2. Calculate the area of the four rectangular sides:
A = 7.1 x 3.2 = 22.72
3. Add the areas of the two rectangular faces and the four rectangular sides:
Total Surface Area = 8.96 + 22.72 = 31.68
