Geometry surface area and volume equations

volume of a prism

h x b (base is what the 2d area of the base shape is)

volume of a pyramid

1/3 (b x h)

volume of a cylinder

h x (pie x r²)

volume of a cone

1/3 x h x pie x r²

volume of a sphere

4/3 x pie x r³

surface area of a prism

the sum of each polygons area added together

surface area of a pyramid

the sum of each polygons area added together

surface area of a cylinder

2 x pie x r (r + h)

surface area of a cone

PIE x r (r +h)

surface area of a sphere

4 x pie x r²
