Answer:
Volume = 280 cubic feet, Surface Area = 304 square feet
Step-by-step explanation:
Volume:
1. The volume of a rectangular prism is calculated by multiplying its length, width, and height. The formula for volume is V = l x w x h, where l is the length, w is the width, and h is the height.
2. Substitute the given values into the formula: V = 8 ft x 7 ft x 5 ft = 280 cubic feet.
3. Therefore, the volume of the rectangular prism is 280 cubic feet.
Surface Area:
1. To find the surface area of a rectangular prism, you need to calculate the area of each of the six faces and then sum them up.
2. The formula for the surface area of a rectangular prism is SA = 2lw + 2lh + 2wh, where l, w, and h are the length, width, and height respectively.
3. Substitute the given values into the formula: SA = 2(8 ft x 7 ft) + 2(8 ft x 5 ft) + 2(7 ft x 5 ft) = 154 + 80 + 70 = 304 square feet.
4. Therefore, the surface area of the rectangular prism is 304 square feet.
