the surface area of a hexigonal pyramid with a slant hight of about 17 and edge of 8

Question

I was given a diagram of a hexagonal pyramid that was marked with the slant hight not complet it was ten and picked up at a coresponding point with a four square root three. I rounded it to seventeen. I need to find the surface area and it is quite frankly blowing my mind.

Answer 1

hexagon base...6 sides, so pryamid hav 6 triangels for sides

triangel base=8 & hite =17

area av triangels=6*(8*17)/2

=3*8*17

=408
