Answer:

448 half inch cubes can fit in the box.

Explanation:

A box is represented by a parallelepiped, whose volume (
V), measured in cubic inches, is represented by the following formula:


V = w\cdot h\cdot l (1)

Where:


w - Width, measured in inches.


h - Height, measured in inches.


l - Length, measured in inches.

If we know that
w = 4\,in,
l = 4\,in and
V = 56\,in^(3), then the height of the box is:


h = (V)/(w\cdot l)


h = (56\,in^(3))/((4\,in)\cdot (4\,in))


h = 3.5\,in

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))


x_(S) = 64

The number of stages within the parallelepiped is:


x_(N) = (3.5\,in)/(0.5\,in)


x_(N) = 7

The total quantity of half inch cubes that can fit in the box is:


n = x_(S)\cdot x_(N)


n = (64)\cdot (7)


n = 448

448 half inch cubes can fit in the box.
