Question

Please help me with number 2

Answer 1

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)=
`L^3`

`18=L^3\\L= √(18) \\L= 3 cm`

hence the dimension is

If the volume must be exactly
`18cm^3` 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
