There are several methods but all involve converting, at some stage, the measurements to yards, square yards or cubic yards.
6 inches = 0.5 feet.
104 x 0.5 = 52 cubic feet.
1 cubic yard = 3 x 3 x 3 = 27 cubic feet
52/27 = 1.926 cubic yards
1 square yard = 3 x 3 = 9 sq feet
104 sq feet = 104/9 = 11.5556 square yards.
6 inches = 0.5 feet = 0.5/3 = 0.1667 yards
11.5556 x 0.1667 = 1.926 cubic yards
An inch is a unit of length. A cubic foot is a unit of volume. The two units are therefore incompatible.
If the interior measures 21" x 11" x 9 inches then the volume is 2,079 cubic inches.
Since the units are incompatible, we can't convert in into in². Inches measures length while inches squared measures area.
cubic metres measures volume, square metres measures area. These are two completely different things.
624 cubic feet
(10 in) x (4 in) x (25 in) = 1000 in3
None. A cubic foot is a three dimensional measure (of volume). Only two measures have been provided.
The total cubic feet the refigirator takes up is all you can calculate from this information. 25''x28''x66''=46200 cubic inches 1728 cubic inches = one cubic foot. 46200/1728=26.73 cubic feet
26.65 cu .ft.
The units are incompatible. A litre measures volume a hectare measures area.
It is not possible to convert from cubic inches to square inches; the former is a measure of volume, the latter a measure of area.
The area of 23 inches times 33 inches is 759 square inches. That cannot be converted to a volume in cubic feet.
