## Can you build a boat out of cardboard?

The only materials allowed in the construction of your boat are cardboard, duct tape, adhesive and water-based paint.

## Will a cardboard boat float?

In case you didn’t know it, a cardboard boat can float.

How much weight can a cardboard boat hold?

To find out how much weight the boat can hold, multiply the volume of your boat in cubic feet by 62.4 lb/ft3, which is the weight of water. For instance, if the boat is 10 feet long, 3 feet wide, and 1 foot tall, the volume is 30 cubic feet. Multiply 30 ft3 by 62.4 lb/ft3, which is equal to 1,872 lbs.

### How do you tape a boat to a deck?

To start off, tape the bottom side of the boat first, and make sure to tape both sides so that the water cannot get in from the bottom and it won’t let water seep into the card board from the top if water was to splash into the insides. Do the same to the sides of the boat as well as to the front and back.

What happens after taping a boat together?
