Find the volume of the right rectangular prism.
To find the volume of a right rectangular prism, you need to multiply the length, width, and height together.
Volume = length x width x height
In this case, the length is 12 inches, the width is 5 inches, and the height is 3 inches.
Volume = 12 in. x 5 in. x 3 in.
Volume = 180 cubic inches
Therefore, the volume of the right rectangular prism is 180 cubic inches.
