How much water does a 72 inch x 22 18 cube hold?

To calculate the volume of a rectangular prism (such as a cube), we need to multiply the length, width, and height of the prism. In this case, the dimensions of the cube are 72 inches, 22 inches, and 18 inches.

Volume = Length × Width × Height

Volume = 72 in × 22 in × 18 in

Volume = 29,952 cubic inches

To convert cubic inches to gallons, we need to divide the volume in cubic inches by 231, which is the number of cubic inches in a gallon.

Volume (gallons) = Volume (cubic inches) / 231

Volume (gallons) = 29,952 cubic inches / 231

Volume (gallons) ≈ 130 gallons

Therefore, a 72 inch x 22 inch x 18 inch cube can hold approximately 130 gallons of water.
