What are the steps to finding the surface area of a rectangular prism with a height of 3.2 in a length of 7.1 in and a base of 2.8 in

Answer 1

Step 1: Calculate the area of the base. Multiply the length (7.1 in) by the width (2.8 in) to get the area of the base, which is 19.88 in².

Step 2: Calculate the area of the sides. Multiply the height (3.2 in) by the length (7.1 in) to get the area of one side, which is 22.72 in². Then, multiply the area of one side by the number of sides (4) to get the total area of the sides, which is 90.88 in².

Step 3: Calculate the total surface area. Add the area of the base (19.88 in²) to the area of the sides (90.88 in²) to get the total surface area, which is 110.76 in².
