Surface area of a cube = [tex]6a^2[/tex]

So 3,750 = [tex]6a^2[/tex]

We need to find the value for [tex]"a^2"[/tex]

Eliminate 6 from both sides using division

[tex]3750/6 = 6a^2/6 625 = a^2 [/tex]

Now we have the area of one side of the square since the area of a square equal [tex]a^2[/tex]

Square root [tex]25 [/tex] and you get one side of the square.

[tex] \sqrt{625}[/tex] =
