Question

A square mosaic is made of small glass squares. If there are 256 small squares in the mosaic how many are along an edge?

Answer 1

answer: 16 small squares

why?
since this is a square mosaic, all four sides have equal numbers of glass squares
if you think about one glass square as one unit, the scenario can be considered through the equation
`256=x^(2)` -- where x is the number of glass squares per side ( remember, area of square =
`x^(2)` )
so, to solve the equation, you find the square root of 256, which is 16!

~hope it makes sense~

Answer 2

To do this, you got to square 256.

The square root of 256 is 16.

Therefore, there are 16 small squares on each edge of the mosaic.

Kinda proof:

o o o o O
o o o o O
o o o o O
o o o o O
o o o o O

25 squares. Square root is 5. 5 along each edge. My work shares same concept.

Extremely unnecessary proof:

o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O
o o o o o o o o o o o o o o o O

There are 256 squares, and you can count 16 on each edge. this shows 16 times 16, or 16 squared, which is 256.
