Nope - cubic inches represents volume. Squareinches represents area.
Cubic inches are a measure of volume, square inches a measure of area and inches a measure of length.
The surface area of a cube that has a volume of 27 cubic inches is: 54 square inches.
A sphere with a surface area of 324pi cubic inches has a volume of: 3,054 cubic inches.
25 cubic inches
*UPDATE*Does it even matter?*UPDATE*None, it can only be cubic feet or cubic inches
231 cubic inches == (presumed that you meant cubic inches, which like gallons is a measure of volume, rather than square inches, which is a measure of area) 1 US gallon = 231 Cubic inches (presuming you meant cubic inches, which like gallons is a measure of volume, rather than square inches, which is a measure of area)
The surface area will be 150 square inches.
Cubic inches measures volume. Square inches measures area. Therefore, you can not compare the two. It is like comparing feet and cups.
The base area cannot be 56 inches because 56 inches is NOT a measure of area - it is a measure of distance.If, the base area was 56 SQUARE inches, the area would be 56*6 = 336 CUBIC inches.
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.
A volume of 453 cubic inches is filled by 1.961 gallons of water.
You cannot convert area to cubic inches. An area is a two dimensional measure whereas cubic inches are a measure of volume (in 3-dimensional space). The two measure different things and, according to basic dimensional analysis, conversion between the two is not valid.
