Answer: About 2,688 ping-pong balls
Step-by-step explanation:
First, we will find how much space a ping-pong ball will take up.
-> A radius of 0.75 inches becomes a diameter of 1.5 inches
-> Then, we will pretend it is a cube with a side of 1.5 inches. Why? We do this because "the balls are stacked adjacent to and directly on top of each other."
V = a³
V = (1.5)³
V = 2.25 inches³
A ping-pong ball will take up 3.375 inches³.
Now, we will find the volume of the room.
V = L * W * H
V = 6 yards * 4 yards * 3 feet
V = 18 feet * 14 feet * 3 feet
V = 756 feet³
Lastly, we will divide the room by a ping-pong ball to find the number of ping-pong balls:
756 feet³ / 3.375 inches³
9,072 inches³ / 3.375 inches³
2,688 ping-pong balls
