How do you find cubed root of 1728 with working?

Answer 1

We know that the cube of 10 is 10^(3) = 1000

So try 11^(3) = 1331 (Too low)

So try 12^(3) = 1728 THE ANSWER!!!! Go No futher.

So the cube root (1728) = 12

Answer 2

1728 = 2*864 = 2*2*432 = 2*2*2*216 = 2*2*2*2*108 = 2*2*2*2*2*54 = 2*2*2*2*2*2*27 = 2*2*2*2*2*2*3*9 = 2*2*2*2*2*2*3*3*3 = 23*23*33

So cuberoot(1728) = cuberoot(23*23*33) = 2*2*3 = 12

Answer 3

12 x 12 x 12 = 1728
