Answer:

The length of a side of the cube-shaped container is 2,016 units

Step-by-step explanation:

step 1

Find the volume of a cube with a side length of 1008 units

The volume of a cube is equal to

[tex]V=b^3[/tex]

where

b is the length side of the cube

we have

[tex]b=1,008\ units[/tex]

substitute

[tex]V=(1,008)^3\ units^3[/tex]

step 2

Find the length side of the cube-shaped container  

Let    

x-----> the length side of the cube-shaped container in units

we know that

The area of the base of the cube-shaped container multiplied by 252 units must be equal to the volume of the cube with a side length of 1008 units

so

[tex]x^{2} (252)=(1,008)^3[/tex]

solve for x

[tex]x^{2} =\frac{(1,008)^3}{252}[/tex]

[tex]x^2=4,064,256[/tex]

[tex]x=\sqrt{4,064,256}[/tex]

[tex]x=2,016\ units[/tex]

therefore

The length of a side of the cube-shaped container is 2,016 units
