Brain Teaser Friday

There is a two foot long plastic boat in the bathtub, the boat is filled with metal nuts and bolts. The boat tips over, dumping the contents into the water. With the nuts and bolts in the water, will the water level in the bathtub rise, fall or stay the same as it was when the nuts and bolts were in the boat?

Um would it lower? Because if the boat has nuts & bolts in it and is 2ft long the surface area and weight of the boat is displacing the water surface and forcing it up? if the bolts fall in- would the water lower?

THE ANSWER:

Due to the weight and construction of the metal nuts and bolts, in this case, the water level will go down. A floating object displaces its weight and a submerged object displaces its volume.

#2-kind of difficult

Assign every letter of the alphabet its numerical value: A=1, B=2, C=3, and so on, up to z=26. Can you think of a familiar 7 letter word whose letter values total only 21?
