Yes, it is possible to construct a regular hexagon with a straight edge and compass I did it in my geometry class.
Answer:

Step-by-step explanation:

<u>Put x = -3</u>

The value of k in <span>
1/2 k+6=4k-8</span>
is 4
Two figure in front
h=16+17 = 33 m
l=18 m
width = 13 m
Volume = lwh = 18*13*33 =7722 m^2
Two figures at the back
h=16 m
l=18+18 =36 m
width = 15 m
Volume = lwh =36*15*16 =8640 m^2
Total volume = 7722+8640 = 16362 m^2
