Question

You have 59 cubic blocks. What is the minimum number that needs to be taken away in order to construct a solid cube with none left over?

Answer 1

Answer: 32 blocks

Step-by-step explanation:

A cube can be made with an equal number of blocks. That is for the length, width and height.

When we calculate it like this:

1 x 1 x 1 = 1

2 x 2 x 2 = 8

3 x 3 x 3 = 27

4 x 4 x 4 = 64 That’s larger than 59, so that’s impossible!

Then we can easily subtract. 59 - 27 = 32 blocks.
