Mentone, indiana, claims to have the world's largest egg sculpture. A 6-foot - tall person standing next to the egg sculpture casts a shadow that is 2 feet long. If the egg casts a shadow that is 4 feet long, how tall is the sculpture?

This item can be answered by the concept of ratio and proportion. The ratio of the sculpture's height and shadow should be proportional or equal to that of the person. Mathematically,

6 ft / 2 ft = h / 4 ft

The value of h in the equation is 12 ft.
