A right rectangular prism is made with 8 small cubes.

Each cube has an edge length of 1/5 inch.
What is the volume, in cubic inches, of the prism?.

The volume of the right rectangular prism = 8 × volume of 1 cube

Volume of cube = a³

✔️Volume of the rectangular prism = 8 × ¹/125

= ⁸/125 cubic inch
