How To Figure Cubic Feet In A Cone Shape

A cone is a familiar shape, if in no other way than from trips to the ice cream stand. As a regular, three-dimensional geometric solid, it has a specific formula you can use to determine its volume. For instance, if you want to figure the cubic feet in a cone for a home or other purpose, all you need is some basic measurements and a calculator to quickly arrive at the solution to your query. Once that is done, you can use the information and apply it to your problem or project.

Step 1

Measure the diameter of the cone. You want the diameter at the base; this will be the very widest part of the cone.

Step 2

Divide the diameter by 2. This yields the radius. For example, if the diameter is 54 inches, the radius is 27 inches.

Step 3

Square the radius. In this example, the result is 729.

Step 4

Measure the height of the cone.

Step 5

Multiply the squared radius by the height. If your height is 83 inches, the result is 60,507.

Step 6

Multiply the result from the previous step by pi. Use 3.14 for pi. For very accurate figuring, use a pi figure with more decimal points. In this example, the result is 189,991.98.

Step 7

Divide the figure from the previous step by 3. In this example, the result is 63,330.66.

Step 8

Divide your figure from Step 7, which indicates the volume in cubic inches, by 1,728. This provides the volume in cubic feet. The result here is 36.65.
