A Penguin experiences a buoyant force that is 12% larger then his weight when diving in the sea to catch a fish. Calculate the penguins density.

When two 18 newton penguins stand on an iceberg floating in the sea, it displaces 5% more seawater than it would normally displace. What is the volume of the iceberg?

A penguin is held under the surface of seawater by a tension of .18 pounds. His density is 1.8 slugs per cubic foot. What is his volume?
