In this article, we are going to discuss a significant concept of cubic feet. We will give a detailed overview of its definition, formula, and significant applications. We will also solve a few examples to apprehend the calculations indubitably.

What is a Cubic Foot?

Cubic feet are a unit of volume that signify the three-dimensional space occupied by an object. It can be expressed as ft³ or cu. ft. The measuring unit known as cubic feet can be applied for calculating the volume of a cube with sides that are each one foot long.

Simply stated, cubic feet represent the volume of space an object takes up in terms of height, breadth, and depth.

How to Calculate Cubic Feet?

When calculating the volume of an object in cubic feet, it is necessary to multiply the object’s length, breadth, and height in feet. The formula is:

Cubic Feet (cu. ft) = Length (ft) x Width (ft) x Height (ft)

It can be used to properly calculate the volume of various things, helping with activities like packing, storing, and designing. Specific conversion factors can be used to convert cubic feet to other units like gallons, liters, or cubic meters.


Example 1:

What will be the volume of a swimming pool if:

H = 23 ft, W = 17 ft, and L = 12 ft


Step 1: Given information:

h = 23 ft

w = 17 ft

l = 12 ft

Step 2: By formula:

V (cu. ft) = l (cu. ft) x w (cu. ft) x h (cu. ft)

V (cu. ft) = 12 (ft) x 17 (ft) x 23 (ft)

V (cu. ft) = 4692 ft3.

Example 2: 

Determine the volume of a carton if:

h = 0.13 m, w = 0.16 m, and l = 0.8 meters.


Step 1: Given information:

l = 0.8 meters

w = 0.16 meters  

h = 0.13 meters

Required data:

V (ft3) =?  

Step 2: Multiply the given parameters by “3.281” to convert them into ft.

l = 0.8 x 3.281 = 2.6248 ft.

w = 0.16 x 3.281 = 0.52496 ft.

h = 0.13 x 3.281 = 0.42653 ft.


Volume (Cu. ft) = length (ft) x width (ft) x height (ft)

Step 3: Put the relevant values:

V (cu. ft) = l (ft) x w (ft) x h (ft)

Volume = 2.6248 ft x 0.52496 ft x 0.42653 ft

Volume = 0.58772 ft3.

A cubic foot calculator could be a handy tool for finding the volume of objects in cubic feet in order to ease up the calculations.

Example 3:

What volume of water would be needed in cu. ft to fill a fish tank if:

l = 3.8 yards, w = 2.3 yards, and h = 1.2 yards.


Step 1: Given information:

l = 3.8 yards, w = 2.3 yards, and h = 1.2 yards

Step 2: Putting the relevant values in the formula:

V = 3.8 yards x 2.3 yards x 1.2 yards

V = 10.488 cu.  yards

Step 3: Now, multiply the obtained result by 27 to determine the volume in cu. ft.

V (cu. ft) = 10.488 x 27

V (cu. ft) = 283.176 ft3
