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.
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 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.
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.
To measure volumetric flow rate, use a flow meter. Cubic feet is a unit of volume, and minute is a unit of time. The rate of volume flow is referred to as volumetric flow rate.
Calculating the capacity of a washer in cubic feet requires a tape measure and a calculator. Switch off the washer and remove any laundry before taking the measurements.
The cubic feet formula depends on the shape of the object for which one is calculating volume, but for a cube, v=a^3, where a is the length of one side in feet. For cylinders and prisms, the formula is the area of the base multiplied by the height.
