What is the volume in cubic inches of a rectangular prism that is 1 foot in length, 1 foot in width, and 1 foot in depth?

To calculate the volume of a rectangular prism, you need to multiply its length, width, and height. In this case, the length, width, and depth are all 1 foot.

Since 1 foot is equal to 12 inches, you can convert the measurements to inches. So, the length, width, and depth of the prism are each 12 inches.

Now, multiply the length, width, and depth:

Volume = Length x Width x Depth
= 12 inches x 12 inches x 12 inches
= 1728 cubic inches

Therefore, the volume of the rectangular prism is 1728 cubic inches.
