What are some formulas for surface area?
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)
There are several formulas for calculating the surface area of different geometric shapes. Here are some commonly used formulas:
1. Rectangular Prism: Surface Area = 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height.
2. Cube: Surface Area = 6s^2, where s is the length of one side.
3. Cylinder: Surface Area = 2πr^2 + 2πrh, where r is the radius of the base and h is the height.
4. Cone: Surface Area = πr^2 + πrl, where r is the radius of the base and l is the slant height.
5. Sphere: Surface Area = 4πr^2, where r is the radius.
6. Pyramid: The formula for the surface area of a pyramid depends on the shape of the base. For example, for a square base: Surface Area = l^2 + 2lw, where l is the slant height and w is the width of the base.
These formulas can be used to find the surface area of different three-dimensional objects.
