Formula:
The surface area (SA) of a three-dimensional object is the sum of the areas of all its faces or surfaces. The formula for surface area varies significantly depending on the shape:
- Cube: SA = 6s2 (where s = side length)
- Rectangular Prism: SA = 2(lw + lh + wh) (where l = length, w = width, h = height)
- Cylinder: SA = 2πr(r + h) (where r = radius, h = height)
- Sphere: SA = 4πr2 (where r = radius)
- Cone: SA = πr(r + √(h2 + r2)) (where r = radius, h = height, and √(h2 + r2) = slant height)
