Understanding the Concept of Cubic Feet with Calculations

Cubic feet, often abbreviated as ft³, is a unit of volume used in the imperial and United States customary systems of measurement. It is a representation of the area filled by a cube with sides of one foot. In daily applications such as building, interior design, and engineering, the volume of things, rooms, containers, and other three-dimensional areas is frequently measured in cubic feet.

In this article, we will discuss the cubic feet with the help of formulas, the different formulas used to find cubic feet, the Conversion method, and the conversion table. Moreover, for a better understanding of the concept of cubic feet concept with the help of detailed example and their solution.

Formula

Three measurements are given we find the volume multiplied by all terms together. We use the cubic feet formula are

Volume = height × width × height

Formula Used to find the calculating cubic feet

Here are four formulas that can assist with calculating cubic feet in different scenarios:

• For Rectangular Objects or Spaces:
  

  Formula: Volume (in cubic feet) = Length × Width × Height

  Use this formula when dealing with rectangular or box-shaped objects or rooms. Measure the length, width, and height in feet, and then multiply them together to find the volume in cubic feet.

• For Cylindrical Objects:
  

  Formula: Volume (in cubic feet) = p × R² × Height

  Use this formula when dealing with cylindrical objects like tanks or pipes. Measure the radius (distance from the center to the edge of the circular base) and the height in feet, and use p (pi, approximately 3.14159) as a constant.

• For Irregular Shapes Using Displacement:
  

  Formula: Volume (in cubic feet) = Initial Volume - Final Volume

  This formula is used when you have an irregularly shaped object placed in a container of known volume. First, fill the container with water and find the initial volume. Then, place the object in the container, and measure the final volume. The difference between the two volumes gives you the volume of the irregularly shaped object in cubic feet.

• For Converting Cubic Meters to Cubic Feet:
  

  Volume (in cubic feet) = Volume in Cubic Meters × 35.3147

  When converting a volume from cubic meters to cubic feet, use this formula. To get the volume in cubic feet, multiply the value in cubic meters by the conversion ratio, 35.3147. These formulas cover various scenarios for calculating cubic feet, whether you're dealing with regular or irregular shapes, cylindrical objects, or converting from other units of volume.

Calculating cubic meters from cubic feet

You can use the following conversion factor when you convert cubic feet into cubic meters.
1 cm³ = 35.3147 c ft³
So, you can use the formula to convert cubic feet (ft³) into cubic meters (m³):
Cubic feet (ft³) / 35.3147= Cubic meters (m³)
To get the equivalent volume in cubic meters, simply divide the number of cubic feet by 35.3147.

Cubic feet to cubic meter: Table representation

Example section

Below are a few examples of finding cubic feet.
Example 1: If the object has a length is 15 inches, 12 feet of width and a height is 20 inches. Examine the volume of the object.

Solution
Step 1:
Given data
Length = 15 inches
Width = 12 feet
And height = 20 inches
Step 2:
Covert all data into feet because the cubic feet formula all values used in feet.
Length= 15/ 12 = 1.25
Width = 12 feet
And height = 20 inches = 20/12 = 1.667
Step 3:
Put all values in the formula to find the volume in cubic feet
Volume = 1.25 × 12×1.667 = 25.005

Example 2: If the object has length is 15 yards, 20 yards’ width and height is 25 yards. Examine the volume of the object.
Solution
Given data
length = 15 yd, width = 20 yd and height = 25 yd
First of all, we have to convert all units to feet (ft):
15 yd ? 45 ft
20 yd ? 60 ft
25 yd ? 75 ft
After conversion value is:
length = 45 ft, width = 60 ft
and
height = 75 ft
Now we have to put values in the above formula:
Cubic Feet = 45 × 60 × 75
Cubic Feet = 202500 ft3

FAQs

In this section, for our better understanding of the concept of cubic feet, we will discuss some frequently asked question and their answer.

Q1. Write down the process of how we convert cubic feet into cubic meters.
ANS: We already know that 1 cubic foot= 0.0283168 m3. So, for conversion, we multiply the volume in cubic feet by this factor to get the equivalent volume in cubic meters.

Q2. Write down the formula for volume in cubic feet.
ANS: The formula Volume (ft3) = Length Width Height is commonly used to determine volume in cubic feet. Combine the feet-based measurements of the object's length, breadth, and height.

Q3. How can I estimate the volume of irregularly shaped objects in cubic feet?
ANS: Use water displacement for things with uneven shapes. By adding a specific volume of water to the container and setting the object inside, we can determine the increased water level. The rise in water level corresponds to the irregular object’s cubic foot volume.
