## Study Notes

### Volume of Prisms and Cylinders

- The formula to find the volume of a prism or a cylinder is V = Bh, where V is the volume, B is the base area, and h is the height.
- This formula applies to both prisms and cylinders because they have two identical bases and a same height.

### Volume of a Cylinder

- The formula to find the volume of a cylinder is V = πr²h, where V is the volume, π (pi) is a mathematical constant, r is the radius of the base, and h is the height.

### Surface Area of Prisms

- The surface area of a prism is defined as the sum of the areas of its faces, including the two bases and the lateral faces.
- The formula for surface area varies depending on the type of prism, but it typically involves finding the area of each face and adding them together.

### Surface Area of Cylinders

- The formula to find the surface area of a cylinder is SA = 2πr(h + r), where SA is the surface area, π (pi) is a mathematical constant, r is the radius of the base, and h is the height.

### Prisms vs Other Solids

- The main difference between prisms and solids like pyramids, cones, and spheres is that prisms have two identical bases, while the other solids have only one base and taper to a point or curve.
