Cubic inches word problem

[Guest]

PROBLEM: An average home is 7'8" Long, 12'2" Wide, 10'1" Tall. Inside the home, there is a small work area for preparing meals, a fire in the center for cooking and heat, and sleeping areas along the wall opposite the work area. What is the average cubic area of the home? _______ cubic inches

[rmiller2015]

7' 8" = 7 * 12 + 8 = 92 inches
12' 2" = 12 * 12 + 2 = 146 inches
10' 1" = 10* 12 + 1 = 121 inches

92 * 146 * 121 = 1625272 cubic inches = 940.5509 cubic feet
