Two Ships
Science brain teasers require understanding of the physical or biological world and the laws that govern it.
There are two ships of equal size and strength. One is made of wood and the other steel. Can you explain which is heavier?
Answer
The ship made of wood is heavier. Since pound for pound steel is so much stronger that wood, the ship made of wood would require a great deal more material for it to be of equal strength.

| Very easy one. What is really meant by strengh should be more specific. Wood got certain advantages that make it stronger than steel depending on what you call strengh. |

| if the ship of wood requires a great deal more material to make it as strong as the ship of steel then it cannot be of an EQUAL size to the ship of steel can it |

| Sure it can dark-prince. The hull of the steel ship would be thinner, while the wooden ship would be thicker, with interior bracing, but the same size. |
