Answer:
C. 2,940 ft³
Step-by-step explanation:
The building is composed of a triangular prism and a rectangular prism
Therefore,
Volume of air in the building = volume of the triangular prism + volume of the rectangular prism
Volume of triangular prism = ½*bhl
b = 4 yards = 4*3 = 12 ft
h = 15 - 9½ = 5½ = 5.5 ft
l = 20 ft
Volume of triangular prism = ½*12*5.5*20 = 660 ft³
Volume of rectangular prism = W*H*L
W = 4 yds = 12 ft
H = 9½ = 9.5
L = 20 ft
Volume of rectangular prism = 12*9.5*20 = 2,280 ft³
✔️Volume of air in the building = 660 + 2,280 = 2,940 ft³

Can you help me I posted a new question that is worth 50 points
Answer:
69 users.
Step-by-step explanation:
First, we need to calculate the amount of seconds in one day.
a) Each hour has 60 minutes and each minute has 60 seconds.
Therefore, one hour has (60)(60) = 3600 seconds.
b) Since the day has 24 hours, we are going to multiply the total amount of seconds per hour by 24.
3600 (24) = 86400 seconds per day.
c) Now that we have the amount of seconds per day, we are going to divide the total amount of users added each day by the amount of seconds per day.
6000000/86400 = 69.44 users per second.
Therefore, 69 users are added, on average, each second.
