There's a large literature on just this problem on the web, so we can't
saddle Dy/Dan with having made it up from scratch. The more usual
constraint is to hold perimeter constant and optimize for volume. My
approach below, of holding area constant, has this other solution, which
has a punch line: a mile wide, inch deep, is way more substantive than a
mile deep, inch wide: the lesson of the cylinder. Over-specialists, take
notice.

The above link includes both constraints as options. There's no use of
calculus demonstrated but there is a sense of a maximum we might compute
exactly, in the perimeter case, so that might be a next stop along the way.

Allowing for more non-linear, not-lock-step explorations of the terrain is
encouraged in STEM. You'll keep coming back to the same topics from
different angles and that's as it should be.
