Step-by-step explanation:
Since the firm was hired to create a box kind of shape, the length, width and height will be the same
i.e volume= L*W*H= (L*L*L)= [tex]L^3[/tex]
[tex]18=L^3\\L= \sqrt{18} \\L= 3 cm[/tex]
hence the dimension is
If the volume must be exactly [tex]18cm^3[/tex] the dimension must be
length= 3 cm,
width = 3 cm and
height = 3 cm
The set of dimension if the company is to use the least materials is
length= 3 cm,
width = 3 cm and
height = 3 cm
