Question

a box has a volume of 30 cubic centimeters. the box is filled with unit cubes, with no gaps or overlaps. each unit cube measures 1 centimeter in length, 1 centimeter in width, and 1 centimeter in height. how many unit cubes fill the box? 10 90 30 33

Explanation:

Step1: Recall volume formula for unit - cubes

The volume of a unit cube is $V = 1\times1\times1=1$ cubic centimeter.

Step2: Calculate number of unit - cubes

The number of unit cubes $n=\frac{\text{Volume of the box}}{\text{Volume of one unit cube}}$. Given the volume of the box is 30 cubic centimeters and the volume of one unit cube is 1 cubic centimeter. So $n=\frac{30}{1}=30$.

Answer:

C. 30
