Answer: 2400 cubic meters
======================================================
Step-by-step explanation:
Assuming the guests are spaced out in a uniform fashion (i.e. they are spaced the same in each direction), then,
- 1 person = 4 m^2 of floor area
- 120 people = 120*4 = 480 m^2 of floor area
In short, 120 people occupy 480 square meters of floor area. So we'll assume that this is the floor area of the pyramidal tent.
V = volume of the pyramid
V = (1/3)*(area of the floor or base)*(height)
V = (1/3)*(480)*(15)
V = 2400 cubic meters
