Question

Each cube in this rectangular prism is 1 cm3.What is the volume of the rectangular prism?

A.40 cm3

B.20 cm3

C.48 cm3

D.9 cm3

Answer 1

The volume of the rectangular prism is b. 20 cubic cm

What is the volume of the rectangular prism?

From the question, we have the following parameters that can be used in our computation:

the rectangular prism

Where, we have

Length = 2

Height = 2

Width = 5

The volume of the rectangular prism is the product of the dimensions

So, we have

Volume = 2 * 2 * 5

Volume = 20 cubic cm

Hence, the volume of the rectangular prism is b. 20 cubic cm

Answer 2

Volume of rectangular prism =
`20\ cm^3`

Explanation:

Given rectangular prism is made up of small cubes of volume 1 cubic centimeter.

To find volume of rectangular prism.

Solution:

Volume of rectangular prism is =
`length* width * height`

We know that all sides of a cube are equal in measure.

So, we will count the number of cubes on each side to get the exact measure.

Length side = 4 cubes = 5 cm

Width side = 2 cubes = 2 cm

Height side = 2 cubes = 2 cm

Thus volume of rectangular prism =
`5\ cm* 2\ cm * 2\ cm`

Volume of rectangular prism =
`20\ cm^3`
