Take 8 times 4.9 and 8 times 3.7, 8 times 4.9 is 39.2 and 8 times 3.7 is 29.6 now all you have to do is subtract them numbers from each other and it gives you the answer of 9.6
Answer: 9.6
Multiply 9 feet times 12 inches and you get 108 inches. Then take 108 inches and divide it by 12 sections, you get 9 inches.
Answer: Each section should be 9 inches long, or 0.75, or 3/4 feet long.
The top and bottom faces are 3 inches by 3 inches.
Area = 3 in. * 3 in. * 2 = 18 in.^2
The front, back, right, and left faces are 3 in. by 6 in.
Area = 3 in. * 6 in. * 4 = 72 in.^2
Total surface area = 18 in.^2 + 72 in.^2 = 90 in.^2
