## 12.1- Exploring Solids

Solids are named after there general shape and their base. For instance, a prism with a base of a pentagon, would be called a pentagonal prism while a prism with a base of a triangle, would be called a triangular prism.

Each solid has 3 characteristic about it. They all have faces, edges, and vertices. Faces are the sides, edges are the lines, and vertices are the points. We use our formula: F + V = E + 2.

## 12.2 - Surface area of a Prism and a Cylinder.

Netting a solid is when we break it down to its individual sides. Check out this worksheet understand.

The surface area of all prisms can be found by using the formual: S = 2B+Ph.

S means Surface Area.

B means Area of the Base

P means the perimeter.

h means the height.

The surface area of all prisms can be found by using the formual: S = 2B+Ch.

S means Surface Area.

B means Area of the Base (πr^2)

C means the Circumference (2πr)

. h means the height.
