I think the three box.sorry if wrong
The regular hexagon has both reflection symmetry and rotation symmetry.
Reflection symmetry is present when a figure has one or more lines of symmetry. A regular hexagon has 6 lines of symmetry. It has a 6-fold rotation axis.

Rotation symmetry is present when a figure can be rotated (less than 360°) and still look the same as before it was rotated. The center of rotation is a point a figure is rotated around such that the rotation symmetry holds. A regular hexagon can be rotated 6 times at an angle of 60°

It is 158 in ^2 because (5 x 8) x 2 + (8 x 3) x 2 + (5 x 3) x 2 = 158
2c-9=c
-9=-c
9=c
Hope that helps!
