The formula to find the volume of a shape depends on the type of shape you're dealing with. Here are some common formulas for different 3D shapes:

1. Cube: $\text{Volume} = s^3$ where $s$ is the length of a side.

2. Rectangular Prism (or Cuboid): $\text{Volume} = l \times w \times h$ where $l$ is the length, $w$ is the width, and $h$ is the height.

3. Cylinder: $\text{Volume} = \pi r^2 h$ where $r$ is the radius of the base, and $h$ is the height.

4. Sphere: $\text{Volume} = \frac{4}{3} \pi r^3$ where $r$ is the radius of the sphere.

5. Cone: $\text{Volume} = \frac{1}{3} \pi r^2 h$ where $r$ is the radius of the base, and $h$ is the height.

6. Pyramid: $\text{Volume} = \frac{1}{3} \times \text{Base Area} \times h$ where $h$ is the height of the pyramid, and the Base Area depends on the shape of the base (e.g., square, rectangle, triangle).
