Answer:
448 half inch cubes can fit in the box.
Explanation:
A box is represented by a parallelepiped, whose volume (
), measured in cubic inches, is represented by the following formula:
(1)
Where:
- Width, measured in inches.
- Height, measured in inches.
- Length, measured in inches.
If we know that
,
and
, then the height of the box is:

![h = (56\,in^(3))/((4\,in)\cdot (4\,in))](https://img.qammunity.org/2022/formulas/mathematics/college/x5bsz9fv0xmbxcbzh28oistmap64vrb8bm.png)
![h = 3.5\,in](https://img.qammunity.org/2022/formulas/mathematics/college/8fdr24py8g93q6fwfcmt9ilsn5yru08vm6.png)
Given that box must be fitted by half inch cubes, the number of cubes per stage is:
![x_(S) = ((4\,in)\cdot (4\,in))/((0.5\,in)\cdot (0.5\,in))](https://img.qammunity.org/2022/formulas/mathematics/college/hgd90i9tg3by3zt14oekzzx3fafo0h9c4a.png)
![x_(S) = 64](https://img.qammunity.org/2022/formulas/mathematics/college/gol019id9ogykvfd2q0sdau7q4hp5ezp9k.png)
The number of stages within the parallelepiped is:
![x_(N) = (3.5\,in)/(0.5\,in)](https://img.qammunity.org/2022/formulas/mathematics/college/63j1wz4tz61z99tt6v2m71ue5cfp2hkrcv.png)
![x_(N) = 7](https://img.qammunity.org/2022/formulas/mathematics/college/gzrq14bfql71cb3yqe5dbquymo8ucx0r9k.png)
The total quantity of half inch cubes that can fit in the box is:
![n = x_(S)\cdot x_(N)](https://img.qammunity.org/2022/formulas/mathematics/college/qchlkfgt1w9ic2zivn7iloaqkddhv2xk4f.png)
![n = (64)\cdot (7)](https://img.qammunity.org/2022/formulas/mathematics/college/hl2c6vldzh65zb78vena9d93elz2cfnhio.png)
448 half inch cubes can fit in the box.
