To determine how many boxes will fit in 15,000 cubic feet, we divide the total volume by the volume of a single box:

$\text{Number of boxes} = \frac{15,000 \, \text{cubic feet}}{0.3 \, \text{cubic feet/box}}$

$\text{Number of boxes} = 50,000$

So, 50,000 boxes will fit in 15,000 cubic feet.

Here are 5 related questions:

1. What if the volume of the box were 0.5 cubic feet?
2. How many boxes will fit if the total volume is 10,000 cubic feet?
3. What if the boxes were rectangular instead of cubic? How would the dimensions change the answer?
4. How much space is left if only 49,500 boxes fit in 15,000 cubic feet?
5. How would you calculate the volume of a box with given dimensions?

Tip: Always ensure the units you're working with match (e.g., cubic feet, cubic meters) when dealing with volume problems.
