how do i find the surface area of a shape?
To find the surface area of a shape, you first need to identify the type of shape you are working with. Here are the formulas for calculating the surface area of common shapes:
1. Cube: Surface area = 6 x (side length)^2
2. Rectangular prism: Surface area = 2lw + 2lh + 2wh
3. Sphere: Surface area = 4πr^2
4. Cylinder: Surface area = 2πrh + 2πr^2
5. Cone: Surface area = πr(r + √(h^2 + r^2))
Once you have identified the shape and its dimensions, plug the values into the appropriate formula and calculate the surface area.
