**Surface area of a cube and rectangular prism**

2
**How to find the surface area of a cube**

SA = Ph + 2B = (12•4) (12) + 2 (12)² = 48 • 12 + 2 (144) = 576 + 288 12 cm = 864 cm² P = the perimeter of the base h = the height of the cube B= the area of the base

3
**How to find the surface area of a rectangular prism**

SA = Ph + 2B = ( ) •10 + 2 (14• 6) 10m = (40) •10 + 2 (84) = 400 + 168 6m = 568m² 14m P= the perimeter of the base h= the height of the prism B= the area of the base
