Hexagonal pyramid

Calculate a regular hexagonal pyramid's volume and surface area with a base edge a = 30 m and a side edge b = 50 m.

Correct answer:

V =  31176.9145 m3
S =  6630.995 m2

Step-by-step explanation:

a=30 m b=50 m n=6  S0​=43​​⋅ a2=43​​⋅ 302=225 3​ m2≐389.7114 m2 S1​=n⋅ S0​=6⋅ 389.7114=1350 3​ m2≐2338.2686 m2  h=b2−a2​=502−302​=40 m  V=31​⋅ S1​⋅ h=31​⋅ 2338.2686⋅ 40=31176.9145 m3
