| Figure | Formula |
|---|---|
| Cube | 𝑆𝐴 = 6𝑠2, where 𝑠 is the side length |
| Prism | 𝑆𝐴 = 2𝐵 + 𝑃ℎ, where 𝐵 is the area of the base, 𝑃 is the perimeter of the base and ℎ is the height |
| Cylinder | 𝑆𝐴 = 2𝐵 + 𝑃ℎ, where 𝐵 is the area of the base, 𝑃 is the perimeter of the base and ℎ is the height |
| Cone | 𝑆𝐴 = 𝐵 + 𝜋𝑟ℎ𝑠, where 𝐵 is the area of the base, 𝑟 is the radius and ℎ𝑠 is the slant height |
| Pyramid | 𝑆𝐴 = 𝐵 + 𝐴(𝑒𝑎𝑐ℎ 𝑓𝑎𝑐𝑒), where 𝐵 is the area of the base and 𝐴(each face) is the area of each face |
| Regular pyramid | 𝑆𝐴 = 𝐵 +½ 𝑃ℎ𝑠, where 𝐵 is the area of the base, 𝑃 is the perimeter of the base and ℎ𝑠 is the slant height |
| Sphere | 𝑆𝐴 = 4𝜋𝑟2, where 𝑟 is the radius |
| Hemisphere | 𝑆𝐴 = 3𝜋𝑟2, where 𝑟 is the radius and the area of the flat side is included |
