What is the Volume of Cubic Foot?
The volume of cubic foot is defined as the volume of a cube with sides of one foot in length. A cubic foot is a unit used to measure a unit volume. In the plural form, it is used as cubic feet. A cubic foot is also used as a measuring unit of unit rate of flow in the case of rivers and also in the case of gases. In the case of solids, a cubical foot helps us to measure its volume using its dimensions in 3-D.
Volume of a Cubic Foot Formula
We already know that volume of any solid is defined as the number of cubic units occupied by it. Therefore, the unit of 'volume' is "cubic units". For example, it can be expressed as m3, cm3, in3, etc depending upon the given units. For any solid with dimensions:
- Length 'l' ft
- Breadth 'b' ft
- Height 'h' ft
The volume of cubic foot = l × b × h = lbh ft3 or cubic foot
How Can We Find the Volume of a Cubic Foot?
- Step 1: Identify the length, breadth, and height of the solid in feet.
- Step 2: Find the product of the three dimensions to get the volume.
- Step 3: Now represent the volume obtained in cubic feet.
Conversion of Volume of a Cubic Foot
To find the volume of a cubic foot, it is not mandatory that the unit of the dimensions must be in feet. In fact, we can have the dimensions in any unit and then convert them to feet. Let's take a look at the different scenarios one by one.
| Units | Conversion to Cubic Foot |
|---|---|
| Cubic yard to cubic foot | As 1 yard = 3 feet, thus, 1 cubic yard = 27 cubic feet |
| Cubic inch to cubic foot | As 1 inch = 0.0833 foot, thus, 1 cubic inch = 0.000578 cubic foot |
| Cubic meters to cubic foot | As 1 m = 3.28084 feet, thus, 1 cubic meter = 35.3147 cubic feet |
Using these measures, we can find the volume of a cubic foot of a dimension of any unit.
Example: Find the volume of a box having dimensions 3 m × 4 m × 5 m.
Solution: Given dimensions of box area, 3 m × 4 m × 5 m.
The volume of box, V = 3 m × 4 m × 5 m = 60 m3
We know that 1 cubic meter = 35.3147 cubic feet.
Thus, 60 m3 = 2,118.882 cubic feet.
The volume of the box is 2,118.882 cubic feet.
