Well it doesn't weigh 10 lbs! Ordinarily, a brick would be considered incompressible, and that is still probable in 5000 ft of water. And assuming that it had no entrained air!
BUT, water at 5000 ft is compressible (for which you'll have to look up an hydrology table) and the volume of water displaced by the brick will now weigh more than that volume would have had at the surface.
And as soon as you have immersed your brick, it will weigh less than it previously did, by the weight of water it displaced. remember Archimedes?
SO your brick would now be slightly more buoyant (weigh less) than it did close to the surface.
In an exam answer, one would usually say 'assuming the brick is incompressible', and 'assume the brick is impermeable'. Of course you could also 'assume that water is incompressible', and eliminate the hydrology tables!
Then proceed with the answer.
One brick weighs 10 pounds.
Depends on the density of the bricks you are referring to. If one brick was one cubic meter and weighed a ton then your answer would be 1. Similarly if it took 3424 bricks to weigh a ton and they were all half a cubic meter, then your answer would be 1712 cubic meters. You require more information.

They weigh 185.2 pounds.
First take the weight in kilograms and simply multiply it by 2.2. This would give you the answer in pounds. So in this case the answer is 6.61 pounds.
He is a at least 560 pounds

6,666,666,666 people weighing an average of 150 pounds each would weigh a total of 1 trillion (1,000,000,000,000) pounds.
10 pounds
On the Moon, you'd weigh 12.24 pounds.
If you weighed 78 pounds on earth, you would weigh 29.4 pounds on mars.
10.02 pounds. Take the weight and multiply it by .167 to find the "Moon weight"
Hmm. Tricky. Probably 100 pounds!!
2195 pounds and 13ounces
They would weigh approx 84,600 pounds-force.
34 pounds.
i think it would probably weigh 50-70 pounds
