To calculate the surface area of various geometric shapes, you need to know the formula for each shape. Here are some of the most common geometric shapes:

  • Cube: To find the surface area of a cube, use the formula 6a², where a is the length of one of the sides of the cube.
  • Rectangular Prism: The surface area of a rectangular prism is given by the formula 2(lw + lh + wh), where l, w, and h are the length, width, and height of the prism.
  • Sphere: The surface area of a sphere is 4πr², where r is the radius of the sphere.
  • Cylinder: To find the surface area of a cylinder, use the formula 2πrh + 2πr², where r is the radius of the base of the cylinder and h is its height.
  • Cone: The surface area of a cone can be calculated using the formula πr² + πrl, where r is the radius of the base of the cone and l is the slant height.
