1. The volume of a rectangular prism can be calculated using the formula $V = l \cdot w \cdot h$ where $l$, $w$, and $h$ are the length, width, and height respectively.
2. For a cylinder, the volume is given by $V = \pi r^2 h$ where $r$ is the radius of the base and $h$ is the height.
3. The volume of a sphere is calculated using $V = \frac{4}{3} \pi r^3$ where $r$ is the radius.
4. In algebraic models, volume can often be expressed as polynomial equations involving dimensions.
5. Understanding how to solve inequalities involving volumes can help in solving real-world problems like determining capacity constraints.
