Perfec t Cubes : Cubes and Cube Roots... How to Cube A Number To cube a number, just use it in a multiplication 3 times... Example: What is cube ? Note: we write down "3 Cubed" as 3 3 (the little " 3 " means the number appears three times in multiplying) Some More Cubes

4 cubed=4343 =4 × 4 × 4=64 5 cubed=5353 =5 × 5 × 5=125 6 cubed=6363 =6 × 6 × 6=216 3 Cubed= 3 =3 × 3 × 3=27 Cube Root A cube root goes the other direction: 3 cubed is 27, so the cube root of 27 is 3

Note: When you see "root" think "I know the tree, but what is the root that produced it?" In this case the tree is "27", and the cube root is "3".

If you cube 5 you get 125: 5 × 5 × 5 = 125 If you cube -5 you get -125: -5 × -5 × -5 =

This is the special symbol that means "cube root", it is the "radical" symbol (used for square roots) with a little three to mean cube root.
