A parcel is to be tied with a length of string in a **normal(?) **way.

Assume that the parcel is a cuboid with square cross section and with a volume (V) of 16000 cm^3. Find an expression for the length of string, L(x), in terms of the side of the square cross section, x

And..

determine the dimensions of the parcel that will minimize the length of string required.

Any help would be greatly appreciated.
