*A square sand box has an area of 75 square feet .*

*Estimate the length of one of the sides of the sand box*

8 squared is 64

9 squared is 81

So the answer is between 8 and 9.

Refine this further. Check halfway between them.

8**.**5 is easy to square. 8**.**5^{2} = 72**.**25

So the answer is **between 8.5 and 9** That's what they call an "estimate"
