Volume of Rectangular Prism Calculator

Using this rectangular prism volume calculator, you can easily calculate the volume of a rectangular prism (cuboid). This online calculator is designed specifically for calculating the volume of rectangular prism geometries.

A prism is a polyhedron (solid) with a congruent and parallel base and top, as well as parallel and identical cross sections to the base.

The geometry of the cross sections of various prisms determines their names. Pentagonal prism, triangular prism, octagonal prism, hexagonal prism, trapezium prism, rectangular prism (cuboid), cylinder prism, and cube prism are examples of prisms based on their shape.

Rectangular Prism Volume Formula

A simple formula can be used to find the volume of a rectangular prism. Use the formula below to find the volume of a rectangular prism.

How to Find the Volume of Rectangular Prism

The required dimensions of the object, such as length, width, and height, are needed to calculate the volume of a rectangular prism. Once these values are determined, the volume of a rectangular prism can be simply calculated using the above-mentioned formula.

We’ve included some solved examples below to help you tackle the rectangular prism volume problems quickly.

Example

1. Calculate the volume of a rectangular prism with an 8-foot height, a 4-foot width, and a 15-foot length.

Solution :

Length = 15 ft
Width = 4 ft
Height = 8 ft

Using the rectangular prism volume formula,

Volume = l x w x h
Volume = 15 x 4 x 8
Volume = 480 ft3

The volume of a rectangular prism is 480 cubic feet.

Example

2. A rectangular prism has a volume of 90 cubic units. If the height and width of the object are 5 and 3 units, calculate the length.

Solution :

Length = ?
Width = 3 units
Height =5 units
Volume = 90 cubic units

Using the rectangular prism volume formula,

Volume = l x w x h
90 = l x 3 x 5
90 = 15 l
l = 90/15
length = 6 units

The length of a rectangular prism is 6 units.
