Question

you are building a raft out of two by fours. How many two by fours do you need in your raft in order for you to float

Answer 1

Answer: 10 pieces of two by four woods.

Explanation:

The number of woods that would be needed depends on the type of design chosen. A more complex design would require more wood to achieve it so it can satisfy the law of buoyancy and float on the water.

10 pieces of two by four would would be enough to build a raft that would float on water.
