Question
Two different types of flat metal sheets will be cut in appropriate sizes and combined to make an open top, square prism shaped box. The cost of 1 cm2 of the metal used in the construction of the side faces of the square prism is 16 TL, and the cost of 1 cm2 of the metal used in the construction of the base is 9 TL. Which of the following are the dimensions of the lowest cost box with a volume of 144cm3?
a)none
b)base edge=2.25cm h=8cm
c)base edge=6cm h=4cm
d)base edge=4cm h=9cm
e)base edge=8cm h=2.25cm
f=base edge=2*(36)^(1/3)cm h=2*(36)^(1/3)cm
