Study Notes
Cubes
Cubic Root
- The cubic root of a number is a value that, when multiplied by itself three times, gives the original number
- Denoted by the symbol √³ or ³√
- Example: ³√27 = 3, because 3 × 3 × 3 = 27
Volume of a Cuboid
- The volume of a cuboid is the amount of space inside the cuboid
- Formula: V = l × w × h, where
- V = volume
- l = length
- w = width
- h = height
- Unit: cubic units (e.g. cubic meters, cubic centimeters)
Surface Area of a Cube
- The surface area of a cube is the total area of all its faces
- Formula: SA = 6s², where
- SA = surface area
- s = side length
- Since all sides of a cube are equal, the surface area is six times the area of one side
