If the diameter of the moon is 3476 kilometers, find its volume. If 1 km^{3} of cheese feeds 100 people and there are 8 billion people on Earth, could the moon feed the whole world? Assume that the moon is a perfect sphere, that it's made entirely of cheese, and that no one is lactose-intolerant.

By this point, we could find the radius from a diameter even when blindfolded with our hands tied behind our backs. The radius of the moon is 1738 kilometers. Just plug it into the formula. *V* ≈ 21,990,642,871 km^{3}
If each cubic kilometer of cheese feeds 100 people, we can convert cheese to people. That's a weird sentence. 21,990,642,871 km^{3} × 100 people/km^{3} = 2,199,064,287,100 people The moon could feed nearly 2.2 trillion people. That means it could feed all 8 billion people in the entire world not once or twice, but about 275 times. Dig in, world. | |
