Question: We want to construct a box whose base length is 3 times the base width. The material used to build
the top and bottom cost $10/ft2 and the material used to build the sides cost $6/ft2. If the box must
have a volume of 50ft determine the width of the box that will minimize the cost of building the box.

yes ok                                            

answer: 3.26019516

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
