In order to calculate cubic feet, you need to find the length, width and height of the desired object. You then multiply these three dimensions in order to get the resultant value of volume, which is written in cubic feet.
The surface area of a cube is the total sum of the area of the six sides that cover it, and it is calculated by using the formula A = 6a^2. Measure the area of one side of the cube. Multiply that number by 6 to arrive at the total surface area of the cube.
Use a standard calculator to convert cubic inches to cubic centimeters by multiplying the measurement in inches by 16.387064. Alternately, an online calculator designed for imperial to metric conversions can be used, such as those at The Calculator Site.
Cubic meters are calculated by finding the volume of an object. Wolfram MathWorld lists 15 volume formulae that aid in calculating an object's volume.
Cubic inches are the expression of the volume of a three-dimensional object. For typical square or rectangular areas, multiple the length of each side in inches, according to Math.com.
Calculate the volume of a refrigerator by measuring the length, width and height of the refrigerator's interior in inches. Multiply the three figures together and convert to feet to arrive at the number of cubic feet.
The formula for calculating cubic inches depends on the geometric shape. For example, the formula for the volume of a rectangular solid is length x width x height, while the formula for a pyramid is (1/3) x base x height, according to Math.com.
