Answer:
The correct answer is:
d. The storage unit can hold 100 boxes that are 1 cubic foot.
Explanation:
When a storage unit is described in cubic feet, it refers to the volume of the unit. Cubic feet is a unit of volume that measures the length, width, and height of a space.
If a storage unit is 100 cubic feet, it means that the total volume of the unit is equivalent to 100 boxes, each measuring 1 foot in length, 1 foot in width, and 1 foot in height (1 cubic foot each).
The other options do not accurately describe what 100 cubic feet means:
a. The size of the unit is not judged as small or large in this context.
b. The number of items a storage unit can hold depends on the size of the items, not just the volume of the unit.
c. While the storage unit can be used for extra materials, this does not specifically describe what 100 cubic feet means.
