Find the volume of the right rectangular prism.

3 in. Height
5 in. Front to back
12 in. Width

To find the volume of a right rectangular prism, you multiply the length, width, and height of the prism.

In this case, the height is 3 inches, the front to back dimension is 5 inches, and the width is 12 inches.

Volume = height x front to back x width
Volume = 3 in x 5 in x 12 in
Volume = 180 cubic inches

Therefore, the volume of the right rectangular prism is 180 cubic inches.
