Question 2

A lidless tank has a square base. Which proportions give the greatest volume for a fixed area of sheet metal? AI reconstruction: ignore thickness, seams and waste; the base side length is b and the vertical wall height is h. Read “height of base” in the original choices as base side length.

Question illustration
  1. Square base; wall height equals base side (h=b)
  2. Square base; wall height twice base side (h=2b)
  3. Square base; wall height half base side (h=b/2)
  4. Square base; wall height three times base side (h=3b)
  5. None of these
