If a closed rectangular box should have volume 27ccm, find the dimensions
that will make the surface area of closed box minimum possible.
Nothing else is said about box...
Of course I need it to know a,b,c. Your generic solution was nice as it applies all-round. I meant, I don't need any data about the box itself(that's what i meant), as it must be a cube. From 27ccm is 3,3,3.
thx again. I guess I can apply this to all similar problems
I prefer to use , perform all the calculations and only at the end substitute the value because :
- it can be applied to any value of
- it allows to find possible mistakes : when I find , I know that this is a homogeneous equation since b is expressed in cm, V0 in cm^3 and aČ in cm. If I use the value of V0, I am losing this possibility.
