Answer:
x = 18/5
y = 18/5
z = 1.8
Step-by-step explanation:
Remember that the volume for the box is given by the formula
V(x,y,z) = xyz = 23.328
Since our cardboard has no lid then the formula for the surface area would be given by
A = xy + 2xz + 2yz.
The function that we want to optimize given the constrain of the Volume is A.
From the volume equation we find that
z = 23.328 / (xy)
we can plug that in A, and we get
If we equal each partial derivative to zero we get
From those equations we get
If you solve that system of equations you get that
x = 18/5
y = 18/5
z = 1.8
