Original
You want to make cylindrical containers to hold 1 liter (1000{{MATH_1}}) using the
least amount of construction material. The side is made from a
rectangular piece of material, and this can be done with no material
wasted. However, the top and bottom are cut from squares of side
{{MATH_2}}, so that {{MATH_3}} of material is needed (rather than
{{MATH_4}}, which is the total area of the top and bottom). Find
the dimensions of the container using the least amount of material.
{{CMD_5}}
The total area of the material spent consists of the area of the lateral side of the cylinder plus the area of two squares of side {{MATH_6}}.
