Final answer:
Without specific measurements, it's impossible to determine how many cubes Tom's Box can hold. Additional information from a prior context is required to solve this question accurately.
Step-by-step explanation:
In order to determine how many cubes Tom's Box can hold, we need to know the volume of the box as well as the volume of one cube. We can then divide the volume of the box by the volume of a single cube to find how many cubes will fit inside the box. Unfortunately, without specific measurements of the box and the cubes, we cannot provide an exact answer to this question. However, if this is a multiple-choice question with a specific context given in a previous part of an assignment or test, then there should be enough information to calculate the box's capacity correctly.
