To find the l.a., you multiply the perimeter of the base (the hexagon) by the height.
l.a. = 60 x 12
surface area is harder :(
you have to find the apothem and all that jazz. sorry i can't help more, good luck!
you basically want to get x on it's own to find out what it equals so,

x = 43
Using the denominator of 3 we know 3/3 would be equal to 1
Subtract 3/3 from 4/3 = 1/3
So 4/3 = 1 and 1/3
The answer is c.
