Answer:
Side of square bottom=6.46 m
Height of box=4.31 m
Step-by-step explanation:
Let s be the side bottom
Height of box=h
Volume of box=
Volume of box=
Cost of bottom=$40 per square m
Cost of sides =$30 per square m
Total cost=
Differentiate w.r.t s
Again,differentiate w.r.t s
Substitute s=6.46
Hence, the cost is minimum at s=6.46
Side of square bottom=6.46 m
Height of box=4.31 m
My belief is that km is smaller than m so 3.6km is less than 3600m i hope my answer helps you in some sort of way
