ANSWER:
72 box with 1-centimeter cubes
Explanation:
To know how many box with 1-centimeter cubes the figure will fit, you must calculate the total volume of the figure in square centimeters.
The volume of salcula by means of the following formula:

Where l is length, w is width, and h is height
l = 6
w = 3
h = 4
Replacing:
![\begin{gathered} V=6\cdot3\cdot4 \\ V=72\operatorname{cm}^3 \end{gathered}]()
Now we calculate the number of boxes, it would be:
![n=\frac{72\operatorname{cm}^3}{1\operatorname{cm}^3}=72]()
