Cubic mile

A cubic mile is a unit of volume that measures the space occupied by a cube with each side measuring one mile long. In mathematical terms, it is calculated as: \[ \text{Cubic Mile} = \text{mile} \times \text{mile} \times \text{mile} = \text{mile}^3 \] To put it into perspective, one cubic mile is equivalent to about 4.168 billion cubic meters or about 1.101 billion gallons.
