Rectangular Prism Definition
A three-dimensional solid structure with six rectangular sides is known as a rectangular prism. The rectangular prism is also known as a cuboid prism. It contains eight vertices, twelve edges, and six faces. The rectangular prism is best represented by bricks, boxes, and books. The form of a rectangular prism is seen in the diagram below.

Edge: An edge is a line segment that connects with two vertices. In a rectangular prism, there are a total of twelve edges. The lengths of these edges vary.
Face: The rectangular sides of a rectangular prism are called faces. In a rectangular prism, there are six faces (top, bottom, right, left, front, and rear). The opposing faces are similar.
Vertex: The vertex is the place where three edges or the corners of the form meet. In a rectangular prism, there are eight vertices in total.
Types of Rectangular Prism
There are 2 Types of a Rectangular Prism
Right Rectangular Prism: A rectangular prism has all of its angles to be right angles. In other terms, the right rectangular prism is a rectangular prism with bases that are perpendicular to each other. The form of a right rectangular prism is seen in the diagram below.

Properties of Rectangular Prism
A rectangular prism forms a rectangular cross-section.
A rectangular prism has 6 rectangular faces, 12 edges, and 8 vertices.
All the opposite faces are in rectangle shape.
It is also known as a cuboid.
Volume of Rectangle Formula
The amount of space occupied by a three-dimensional object is called the volume of that object. The volume of a rectangular prism represents the amount of space it occupies. In other words, the volume of a rectangular prism is defined as the number of units utilised to fill it. A cubic unit is a unit of volume.
Volume of Rectangle Formula in Maths
The volume of rectangle formula in maths is given by:
Volume of Rectangle formula (V)= l × w × h.
Here,
l signifies length of the rectangular prism
B signifies the base of a rectangular prism
w is the width of a rectangular prism
Volume of a Rectangular Prism Formula
The volume of the rectangle formula is the product of length (l), width (w), and height (h). It is denoted by V.

Therefore, the volume of rectangular prism formula can be written as:
Volume of a Rectangular Prism formula (V)= length × width × height
Or
Volume of Rectangle formula (V)= l × w × h
Where,
l is the length of a rectangular prism
B is the base of a rectangular prism
W signifies the width of a rectangular prism
Area of a Rectangular Prism Formula
Rectangular prism area formula (S) = 2(lw + lh + wh)
Solved Examples
Let's Solve Some Examples Based on the Above Formulas.
Ex.1. The length, width, and height of a rectangular prism are 16 cm, 12 cm, and 8 cm, respectively. Find the volume of a rectangular prism?
Solution:
Given, length = 16 cm,
width = 12 cm,
height = 8 cm.
By the volume of prism formula, we have
Volume = l*w*h
= (16*12*8) cm3
= 1536 cm3
Hence the volume of a rectangular prism is 1536 cm3
Ex.2. The length, width, and height of a rectangular prism are 24 cm, 21 cm, and 12 cm, respectively. Find the volume of a rectangular prism?
Solution:
Given, length = 24 cm,
width = 21 cm,
height = 12 cm.
By the volume of rectangular box formula, we have
Volume = l*w*h
= (24*21*12) cm3
= 6048 cm3
Hence the volume of a rectangular prism is 6048 cm3
Ex.3. The length, width, and height of a rectangular prism are 4 cm, 5 cm, and 2 cm, respectively. Find the volume of a rectangular prism and also find the surface area of a rectangular prism.
Solution
Given, length = 4 cm,
width = 5 cm,
height = 2 cm.
By the volume of a rectangular prism formula, we have
Volume = l*w*h
= (4*5*2) cm3
= 40 cm3
Hence the volume of a rectangular prism is 40 cm3
Using the surface area of a rectangular prism formula, we have
Rectangular prism area formula (S) = 2(lw + lh + wh)
Rectangular prism area formula (S) = 2(45 + 42 + 52)
Rectangular prism area formula (S) = 76 m2
Hence the surface area of a rectangular prism is 76 m2
