Linear units, like inches, can't be converted to cubic units. If they could, then you'd be able to calculate your height in gallons.
It is: width times length times height measured in cubic units
A rectangle is two dimensional and cannot be cubic, but a three dimensional rectangle ( a rectangular prism ) can be cubic.
The shape in question is not a rectangle but a rectangular prism. Its volume is 12.5*10*8 = 1,000 cubic units.
The area of a rectangle is (length) multiplied by (width). The units don't matter. Just make sure that 'length' and 'width' are both measured in the same unit, whatever the unit is.
Linear units, like inches, can't be converted to cubic units. If they could, then you'd be able to calculate your height in gallons.
21*14.5*7.5 = 2283.75 cubic units
Area in square units = base*height
If you mean a width of 5 units then the volume is: 9*5*6 = 270 cubic units
It is: width times length times height measured in cubic units
This is not a valid conversion. Cubic units is a measure of volume while square units is a measure of area.
Volume in cubic units = pi*radius2*height
Measure its dimension in metric units.
A rectangle is two dimensional and cannot be cubic, but a three dimensional rectangle ( a rectangular prism ) can be cubic.
Length x width x depth = cubic volume
The volume of a rectangle is measured in cubic units because it represents the amount of space enclosed within the three-dimensional shape. By measuring in cubic units, we can account for all three dimensions (length, width, and height) of the rectangular prism or solid shape.
80 cubic unitsUsing the formula bh/3, the base is found to be 30 square units and the height is given as 8 square units. Plugged into the equation, 30*8/3 equals 80 cubic units.
