1. 10.5 Surface Area of Prism

2. Surface Area
Sum of the areas of the base(s) and the lateral faces of the space figure.

3. Surface Area Formula for Rectangular Prism Using Separate Surfaces
Find the area of each face (bh) and add together
Top+Bottom+ right+ left+front + back Or
2(Top) +2(left)+ 2 (front)

4. Surface Area Formula for Nets
SA=Lateral Area +2 (Base)
SA= LA +2B

SA= 2(Base:triangle) +left(rectangle) +front(rectangle) +back(rectangle)
SA= LA to 2 (B)

7. Find the Surface Area Using Separate Surfaces
Bases:
2(1/2) (4) (3)= 12
Left face:
3(8)=24
Front face:
(8)(5) =40
Back face:
(4)(8)=32
=108in²
