Fluid statics

If you tried to nonchalantly smuggle gold bricks by filling your backpack, whose dimensions are 60cm x 25cm x 15cm, what would its mass be?

The specific gravity of ice is .917, whereas that for seawater is 1.025. What fraction of an iceberg is above the surface of the water? *note- if possible, please explain this in the simplest way you can- i'm not naturally a science kinda gal! Thanks :)

A 3.15kg piece of wood (SG= .50) floats on water. What minimum mass of lead, hung from it by a string, will cause it to sink? *note- please explain this in the simplest way possible if you can! thank you :)

A 5/8 inch (inside) diameter garden hose is used to fill a round swimming pool 6.1m in diameter. How long will it take to fill the pool to a depth of 1.2m if water issues from the hose at a speed of 0.33m/s? *note- please explain this in the simplest way possible if you can! thank you :)

What gauge pressure in the water mains is necessary if a firehose is to spray water to a height of 15m?
