Formula Reference Sheet
This chapter
Volume
| Rectangular solid (box) | V = l × w × h |
|---|---|
| Cube, edge s | V = s³ |
| Cylinder | V = πr²h |
Surface area
| Rectangular solid | SA = 2(lw + lh + wh) |
|---|---|
| Cube, edge s | SA = 6s² |
| Cylinder (total) | SA = 2πr² + 2πrh = 2πr(r + h) |
Diagonals
| Space diagonal of a box | d = √(l² + w² + h²) |
|---|---|
| Space diagonal of a cube, edge s | d = s√3 |
| Face diagonal | √(l² + w²) for that face |
