What are some formulas for surface area?

Answer 1

1. Rectangular prism: 2lw + 2lh + 2wh
2. Cube: 6s² (where s is the length of one side)
3. Sphere: 4πr² (where r is the radius)
4. Cylinder: 2πr² + 2πrh (where r is the radius and h is the height)
5. Cone: πr² + πrl (where r is the radius and l is the slant height)
6. Triangular prism: bh + (a * s) + (b * s) + (c * s) (where b, h, and a are the base and height of the triangle, and s is the length of the sides)
7. Right pyramid: ½Pl + B (where P is the perimeter of the base, l is the slant height, and B is the area of the base)
