Find out about the difference between square and cube numbers with this Bitesize Primary Second Level Maths guide. The square numbers up to 100 are: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.
It is easy to work out the cube root of a perfect cube, but it is really hard to work out other cube roots. Example: what is the cube root of 30? Well, 3 × 3 × 3 = 27 and 4 × 4 × 4 = 64, so we can guess the answer is between 3 and 4.When you cube a number, you raise it to an exponent of 3. For example: 2^3 = 2*2*2 = 8. A cube root reverses this process. You are being asked to find the number that was originally "cubed". For example: cube root (8) = 2 because 2^3 = 8. Hope this helps. 1 comment. How many perfect cubes you can find from 1 to 100? How many from −100 to 100? Solution. 1 3 = 1. 2 3 = 8. 3 3 = 27. 4 3 = 64. Thus, there are 4 cubes from 1 to 100. Now, 0 3 = 0. . 475 278 320 38 54 377 19 306
