Answer:
1041.6
Step-by-step explanation:
The volume of a pyramid is V=b x h x 1/3 . b is the area of the base and h is the height. V=124 x 25.2 x 1/3 This can simplify to V=3124.8 x 1/3 . You could also just divide by 3. You will get 1041.6
36√3
using sin rule
72/sin90 = x/sin60
or sin60 = opp/hyp. = RH/ 72 (sohcahtoa)
RH = 72sin60
