3. Segment AB has endpoints at (-2,3) and (10,7). What is the equation of the perpendicular
bisector of that segment?

The density of the cube is 40

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square
