A boat with higher density than water will float better.

True

False

A boat that is wide and flat will generally hold more pennies before sinking than one that is deep and narrow.

True

False

A boat's ability to float is only affected by its weight, not its volume.

True

False

Adding pennies to the boat increases its density.

True

False
