Question

How can you find the surface area of prisms?

Answer 1

I'll list the equations for some types of prisms, hope this helps.

• Cube:
  `S=6s^2`, where S = surface area and s = side measure.

• General prism:
  `S=2B+L`, where B is the area of one base.

• Right rectangular:
  `S=2lw+2lh+2wh`, where l is length, w is width, and h is height.

• Pyramid:
  `S=((1)/(2))lP+B`, where P is perimeter of the base, B is the base area, and l is slant height.

Honorable mentions:

Sphere:
`S=4\pi{r}^2`

Cone:
`S=L+B=\pi{rl}+\pi{r}^2`, where r is radius of the circular base

Cylinder:
`S=L+2B, \mbox{ or } S=2\pi{rh}+2\pi{r}^2`, where r is radius, and h is height.
