Calculating the volume of cubes and rectangular prisms is easy when you know the right formulas. Let’s break it down!

1. Cube Volume: The formula for figuring out the volume of a cube is simple: $V = s^3$ In this formula, $s$ stands for the length of one side of the cube. Since all the sides are the same, you just multiply the side length by itself three times.

2. Rectangular Prism Volume: For rectangular prisms, which you can think of as stretched-out cubes, the formula is: $V = l \times w \times h$ Here, $l$ is the length, $w$ is the width, and $h$ is the height. You simply multiply these three numbers together.

Keeping these formulas in mind is really useful for solving geometry problems. Once you practice a bit, they’ll become really easy to remember!
