Answer:
![C=27inch\ by\ 27inch](https://tex.z-dn.net/?f=C%3D27inch%5C%20by%5C%2027inch)
Step-by-step explanation:
Squares ![h=4inch](https://tex.z-dn.net/?f=h%3D4inch)
Volume ![v=1444in^3](https://tex.z-dn.net/?f=v%3D1444in%5E3)
Generally the equation for Volume of box is mathematically given by
![V=l^2h](https://tex.z-dn.net/?f=V%3Dl%5E2h)
![1444=l^2*4](https://tex.z-dn.net/?f=1444%3Dl%5E2%2A4)
![l^2=361](https://tex.z-dn.net/?f=l%5E2%3D361)
![l=19in](https://tex.z-dn.net/?f=l%3D19in)
Since
Length of cardboard is
![l_c=19+4+4](https://tex.z-dn.net/?f=l_c%3D19%2B4%2B4)
![l_c=27in](https://tex.z-dn.net/?f=l_c%3D27in)
Therefore
Dimensions of the piece of cardboard is
![C=27inch\ by\ 27inch](https://tex.z-dn.net/?f=C%3D27inch%5C%20by%5C%2027inch)
