The exterior of a refrigerator is shaped like a rectangular prism, and measures 2 2/3ft wide and 5 1/2 feet high by 2 1/2 feet d
larisa86 [58]
Volume = (2 2/3 ft)*(5 1/2 ft)*(2 1/2 ft)

2 2/3 ft = 8/3 ft
5 1/2 ft = 11/2 ft
2 1/2 ft = 5/2 ft

Volume = (8/3)*(11/2)*(5/2)
Volume = (88/6)*(5/2)
Volume = (440/12) = 36 8/12 = 36 2/3

<u><em> . . . Volume = 36 2/3 ft³</em></u>
