the dimensions of Mr. Tai's living room are 10 ft * 18 ft * 8 ft, and the dimensions of his family room are 14 ft x 20 ft x 8 ft. What is the total volume in cubic feet of the two rooms?
The volume of the living room is 10*18*8=1440 cubic feet and the volume of the family room is 14*20*8=2240 cubic feet. The sum of the two volumes is 1440+2240=3680 cubic feet.
