3 <p>The volume of a rectangular prism is the total space it occupies or the number of cubic units it can hold. A rectangular prism is a 3D shape with six rectangular faces. To find the volume of a rectangular prism, we multiply its length, width, and height. In real life, kids relate to the volume of a rectangular prism by thinking of things like a shoebox, a book, or a cereal box. In this topic, let’s learn about the volume of rectangular prisms.</p>

4 <h2>What is the volume of a rectangular prism?</h2>

5 <p>The volume<a>of</a>a rectangular prism is the amount of space it occupies.</p>

6 <p>It is calculated by using the<a>formula</a>: Volume = Length × Width × Height Where 'Length,' 'Width,' and 'Height' are the dimensions of the rectangular prism.</p>

7 <p>Volume of Rectangular Prism Formula A rectangular prism is a 3-dimensional shape where the length, width, and height can be different.</p>

8 <p>To calculate its volume, you multiply the length by the width by the height.</p>

9 <p>The formula for the volume of a rectangular prism is given as follows: Volume = Length × Width × Height</p>

10 <h2>How to Derive the Volume of a Rectangular Prism?</h2>

11 <p>To derive the volume of a rectangular prism, we use the concept of volume as the total space occupied by a 3D object.</p>

12 <p>The volume can be derived as follows: The formula for the volume of any rectangular prism is: Volume = Length × Width × Height Each dimension can be different, so you multiply these three measures to find the volume.</p>

13 <h2>How to find the volume of a rectangular prism?</h2>

14 <p>The volume of a rectangular prism is always expressed in cubic units, for example, cubic centimeters (cm³), cubic meters (m³).</p>

15 <p>Multiply the length, width, and height to find the volume.</p>

16 <p>Let’s take a look at the formula for finding the volume of a rectangular prism: Write down the formula Volume = Length × Width × Height The length, width, and height are the dimensions of the rectangular prism.</p>

17 <p>Once we know these values, substitute them into the formula Volume = Length × Width × Height to find the volume.</p>
