| Term | Definition |
|---|---|
| 2πr | circumference of a circle |
| 1/2 d1d2 | area of a rhombus |
| πr² | area of a circle |
| s² | area of a square |
| 1/2 ap | area of a regular polygon |
| h(b1+b2)/2 | area of a trapezoid |
| Ph | lateral area of prism |
| La+2B | Total area of a prism |
| Bh | volume of prism |
| 6e² | total area of a cube |
| e³ | volume of a cube |
| 1/2 Pl | surface area of a pyramid |
| LA+B | total area of a pyramid |
| 1/3 Bh | volume of a pyramid |
| Ch | Lateral area of cylinder |
| LA+2B | Total Area of a cylinder |
| Bh | volume of cylinder |
| 1/2Cl | Lateral Area of a Cone |
| LA+B | total area of a cone |
| 1/3Bh | volume of a cone |
| 4/3 πr³ | volume of a sphere |
| a²+h²=l² | slant height |
| Cube | SA = 6(e squared) V = e cubed |
| Rectangular Prism | SA = 2(lw + wh + lh) V = Bh |
| Prism | SA = Sum of the Area of the Bases OR Perimeter of the base times the height + area of two bases V = Bh |
| Cylinder | SA = 2pi(radius squared) + 2pi(rh) V = pir squaredh |
| Pyramid | SA = Sum of the areas of the faces V = 1/3 Bh |
| Cone | SA = pi*r (l+r) V = 1/3 pir squaredh |
| Sphere | SA = 4pir squared V = 4/3 pi*r cubed |
