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.
