Answer:
13
Step-by-step explanation:
56 divided by 7 equals 8
210 divided by 10 equals 21
And if you subtract 21-8 you get 13 #helping the 3rd graders
The area of the box is
which we want to minimize subject to the constraint .
The Lagrangian is
with critical points where the partial derivatives are 0:
Notice that
Substituting the latter into either or will end up suggesting that is infinite, so we throw out this case.
If , then
We ignore the case where because that would make the volume 0. Then
so we have one critical point at
which give a minimum area of about 1829.41 sq. cm.
