The answer depends on how wide and deep it is!
This question cannot be anwsered. Volume cannot be converted to length without some other data.
IMPOSSIBLE to answer ! The dimensions could literally be anything - so long as the capacity remained the same !
4.5 ft * 2.5 ft * 2 ft = 22.5 ft3 =======
26.65 cu .ft.
They are referring to the volume, in this case of an approximate rectangle. So say your refrigerator was 6 feet tall (inside not outside), and 3.5 ft across and 3.5 ft deep. 6ft * 3.5ft * 3.5ft = 21 ft3 which is 21 cubic feet.
6,084*pi cubic feet or about 21,364.56 cubic feet.
Any value that you like. By selecting a suitable cross-sectional area, the height can have any value.
300 feet.
4x4x3 = 48 cubic feet
0.135 cubic feet
No-one knows.
