Study Notes

Solid Figures Formulas

  • Cube: The surface area is 6s², where s is the side length of the cube.
  • Rectangular Prism: The surface area is (lw + lh + wh), where l is the length, w is the width, and h is the height.
  • Pyramid: The surface area is (2(bh) + b²), where b is the base and h is the height.
  • Cylinder: The surface area is 2Ï€r (r + h), where r is the radius and h is the height.
  • Cone: The surface area is Ï€r (l + r), where r is the radius and l is the slant height.
  • Sphere: The surface area is 4Ï€r², where r is the radius.
