Question 1

How many golf balls fit in a Boeing 747?

Accepted Answer

It depends on model, interior configuration, and packing efficiency. The calculator estimates using cabin/cargo volume and a packing factor.

Question 2

What packing efficiency should I use?

Accepted Answer

Random packing of spheres is about 64% (Kepler conjecture). Real interiors reduce this due to seats and curves.

Question 3

Do we include the cockpit and tail sections?

Accepted Answer

You can choose to include or exclude them. Volume near tapered sections is less usable.

Question 4

What about ball size?

Accepted Answer

Standard golf balls have a diameter of about 42.67 mm (1.68 in).

Question 5

Is this exact?

Accepted Answer

No—it's a **Fermi estimate** for fun; the result is an order-of-magnitude approximation.
