10.5 Surface Area of Prism
Surface Area Sum of the areas of the base(s) and the lateral faces of the space figure.
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)
Surface Area Formula for Nets SA=Lateral Area +2 (Base) SA= LA +2B
Using Nets Separate Surfaces Top 3 L Front R Back 3 4 5 4 5 4 5 B h L Front R Back 3 4 5 4 5 4 5 P = 18 B Top & Bottom 4 Left & Right Front & Back
Surface Area for Triangular Prism Separate Surface net SA= 2(Base:triangle) +left(rectangle) +front(rectangle) +back(rectangle) SA= LA to 2 (B)
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 12+24+40+32 =108in²
