Question

Please help me with number 2

Answer 1

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)= $L^3$

$18=L^3\\L= \sqrt{18} \\L= 3 cm$

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
