## How do you remember the surface area and volume formulas?

Surface Areas And Volumes

1. To find the surface area of a solid, add the areas of all the faces. You can remember the formula as sum of areas of the all the faces.
2. Volume of a prism is area of its base times height.
3. Volume of a pyramid is one third of area of its base times height.

What are the formulas for area and surface area?

Variables:

Surface Area Formula Surface Area Meaning
SA=2B+Ph Find the area of each face. Add up all areas.
SA=B+12sP Find the area of each face. Add up all areas.
SA=2B+2πrh Find the area of the base, times 2, then add the areas to the areas of the rectangle, which is the circumference times the height.
