What is Cubic Feet Calculator
A tool that is used to calculate is a calculator. Based on the functions and options, there are different types of calculators. We use calculators to calculate the volume of any three-dimensional object. The length, width and height of the 3D object is used to calculate the volume using a cubic feet calculator.
How to Use the Cubic Feet Calculator
Let’s talk more about how to use the cubic feet calculator. The steps to use a cubic feet calculator are given below:
Step 1: Open the cubic feet calculator. Using the appropriate unit, enter the values for length, height and width.
Step 2: After clicking on ‘convert’, volume in cubic feet will be displayed.
Common Mistakes and How to Avoid Them When Using the Cubic Feet Calculator
When using calculators it’s possible for students to make small mistakes, here are a few common mistakes and ways to avoid them
Mistake 1
Confusion with units
When using cubic feet calculators, students should check and add the units in the calculators. Sometimes instead of feet, they will add inches, which can give a wrong answer. So check the units properly.
Mistake 2
Confusion with dimension
Students often make mistakes in dealing with dimensions, basic mistakes like considering length as width or vice versa. It is advisable to label the dimensions clearly before calculation.
Mistake 3
Errors in converting fractions to decimals
Students can get confused when converting fractions to decimals. Writing 1½ as 1.2 instead of 1.5 would lead to different answers. Therefore, before entering the value into the calculator, make sure you convert the fraction to decimal value.
Mistake 4
Entering wrong values in calculators
Sometimes, students enter 45 instead of 46 in the calculator, which results in a wrong calculation. So students should recheck the values before calculating them.
Mistake 5
Mixing up units
Mixing up units such as using feet and inches without conversion leads to errors. When solving questions using two different units, students need to make sure to convert the units to one standard unit to avoid confusion.
Cubic Feet Calculator Examples
Problem 1
Calculate the volume of a rectangular box. Where the length, width, and height are 4 feet, 3 feet, and 2 feet respectively.
The volume of the rectangle box is 24 cubic feet
Explanation
The volume of a rectangle is calculated by multiplying length, width, and height.
Here, length = 4 feet, width = 3 feet, height = 2 feet
Volume = lwh
= 4 × 3 × 2 = 24 cubic feet
Problem 2
If the length of the edge of a cube is 5 cm. Find the volume of a cube
The volume of a cube is 125 cubic cm
Explanation
The volume of a cube = edge3
Here the edge = 5 cm
The volume of a cube = 53
= 5 × 5 × 5 = 125 cubic centimeters.
Problem 3
The rectangle tank is of length 25 feet, 10 feet width, and height 5 feet. Find the volume of a tank.
The volume of the tank is 1250 cubic feet
Explanation
The volume of the rectangular tank = lwh
Here, l = 25, w = 10, and h = 5
Therefore, the volume of tank = 25 × 10 × 5 = 1250 cubic feet
Problem 4
Calculate the volume of a cylinder with a radius of 36 cm and height of 36 cm.
The volume of cylinder = 146499.84 cm3
Explanation
Volume of cylinder = πr2h
Here, r = 36 cm, h = 36 cm
Volume = π × 362 × 36 = 3.14 × 36 × 36 ×36 = 146499.84 cubic centimeters
Problem 5
What is the volume of a pyramid with a base of 6 feet by 4 feet and a height of 9 feet?
The volume of a pyramid is 72 cubic feet
Explanation
The volume of a pyramid = â…“ lwh
Here l is length, w is the width of the base, and h is height,
Therefore, volume = â…“ × 6 × 4 × 9 = 72 cubic feet

Glossary of Terms for the cubic feet Calculator
- Volume: The space occupied by a three-dimensional object is the volume. For example, the volume of a cube is s3
- Units: The way of measuring the physical qualities of an object is the unit. There are standardized and non-standardized units of measurement. For example, meters, kilograms, feet, and so on
- Feet: Feet is the standard unit of measurement, it is used to measure length. For example 1 feet =12 inch
- Inch: Inch is the unit of measurement of length. 12 inches is equal to 1 foot.
- Three-dimensional object: The objects with three dimensions, length, height, and width are three-dimensional object
