# The Formula

Use the $\frac{1}{3}$-unit cubes to build a prism with a length of 1$\frac{2}{3}$ units, a width of 1$\frac{1}{3}$ units, and a height of $\frac{2}{3}$ unit.

- How many $\frac{1}{3}$-unit cubes fit inside the prism?
- What is the volume of each $\frac{1}{3}$-unit cube?
- What is the volume of the prism?
- Does the volume formula
*V*=*lwh*work for this prism?
