How Many Ping Pong Balls fit in a 747?

How Many Ping Pong Balls fit in a 747

We’re seeking the answer to how many ping-pong balls fit in a 747. The volume of the ping-pong ball is the first thing we must determine.

As per calculations, a 747 can hold nearly 50 million Ping Pongs. However, A standard ping-pong ball has a diameter of 40 mm (1.5 inches) and weighs 2 g (0.07 ounces). 

We can run some computations to solve this question by using these calculations. Because there are around 546 ping pong balls per cubic foot, a 747’s internal capacity can contain approximately 1 million ping pong balls.

To equal, the number of ping-pong balls in one cubic meter, around 18 billion ping-pong balls would be required.

However, it is difficult to conceive so many small round objects crammed into such a small space. For instance, if a ping-pong ball is the same size as an orange, a 747 could contain nearly 500 million oranges!

To put it another way, counting them at 100 every minute would take more than three months to reach the 18 billion mark.

The Volume of the Ping-Pong Balls

The Volume of the Ping-Pong Balls

 Calculate the volume of the airplane by dividing its volume by the size of a ping-pong ball.

r2h is the formula for the cylinder.

Based on a radius of 1 meter and a length of 33 meters.

The figure you get is simply the volume of the Boeing divided by the volume of the ball.

When you pack balls, there will always be voids between them, reducing the number of balls you can fit (unless you have balls of smaller sizes that can fill the voids between balls of bigger sizes). 

To account for the voids, you need to multiply your number by a factor of 0.75. This would explain the situation where balls are packed to their maximum density. If you don’t believe this is the case, multiply by something like 0.6. This 75% element, in my opinion, is significant enough to be considered.

Computations and Assumptions of the Ping Pong Balls

  • The Boeing 747 has a length of just over 70 meters.
  • The cabin is 6.08 meters wide.
  • A ping-pong ball has a diameter of 4 cm.
  • The 747 is comparable to a 70 m x 6.08 m cylinder in terms of volume.
  • The fuselage’s tapering may partially counter the crew cabin’s hump.
Computations and Assumptions of the Ping Pong Balls


The volume of a single ping-pong ball is used to compute the number of ping-pong balls. For the exact amount, there is no reputable source. The closest is, which says it is 0.3181 cubic cm or 2 (25.4cm) x 3, with 25.4cm being the diameter of a ping-pong ball (in cm).

However, the plane’s volume is approximately 4,532,149 cubic feet (5,344 ft). South African Airways’ 747s can carry 24 standard pallets per flight. The plane has sixteen pallets in the front and eight in the back. Each typical pallet measures 96 inches long, 96 inches wide, and 80 inches tall, containing 8413 cubic feet (567literss).

As a result, one plane can carry 19,712 pallets or 1,129,408,000 pieces of goods weighing 688,368 million pounds.

  • Volume = length x cross section in 747, so V = L x R2 = 70 x (6.08/2)2 = 2,032 cubic metres.
  • Ping pong ball volume = 4/3 r3 = 4/3 x 0.043 = 0.000268082 cu
  • The volume is 747 cubic meters multiplied by 74% Equals 1504 cubic meters.
  • 747 * 64% = 1301 cubic metres is the volume.
  • Table tennis balls have an efficient density of 1504 / 0.000268082 = 5610223.
  • 1301 divided by 0.000268082 equals 4852992 Ping pong balls are packed at random.

If the plane is not full;

The volume of a 747 divided by one ping-pong ball equals the number of balls in a 747.

  • Assume the main body of the 747 is a cylinder
  • The estimated length of 100 m,
  • Radius 3 m
  • Volume = pie (3) x 32 x 100 = 2700 cubic meters,
  • 10% to include the volume of two huge wings, four jets, elevators, tires

A 747’s overall volume is 3000 meters, or 3 x 109 cubic centimeters. 4/3 x pie x r3 = VA Ping-Pong ball with a radius of 2 cm has a volume of 4/3 x 3 x 8 v = 32 cubic centimeters.

Final Words

The transportation of ping pong balls is quite expensive. A 747 can hold approximately a 50million ping pong balls (assuming it has 400 seats). The ping pong ball’s volume would be 47.916 r3)/3. This is the largest plane ever built. Around 30 planes of this type have been built in history. 

Now I hope you cleared all the points about how many ping pong balls fit in a 747!
