Pu ≈ 19.816 g/cm³
so
1 ft³ · 19.816 g/cm³ · (12 in/ft)³ · 2.54 (cm/in)³ ≈ 561,127 gms
or about 1,237 lbs
It weighs about 112 pounds
Depends on the size of the aquarium. Water weights 10 pounds per gallon.
1 plutonium (solid) gallon = 71,337 kg
According to the related link, PHYSLINK.COM, "1 cubic foot of air at standard temperature and pressure assuming average composition weighs approximately 0.0807 lbs". The weight of air is highly dependant on the air temperature and barometric pressure.
Lithium is a bit more than half as dense as water. Its relative density -- or, if you prefer, specific gravity -- is 0.53. So, if you know how much a cubic foot of water weighs, multiply that value by 0.53. BTW, one gallon of water (at 4 degrees C) weighs 8.34 pounds, and one cubic foot of water contains 7.48 gallons. (I know that because WikiAnswers told me.) Now you've got all the info you need to make the calculation.

once cubic inch of plutonuim is about 715 pounds 1 cubic inch = 16,387 06 cm2 Density of plutonium: 19,816 g/cm3 The weight of 1 cubic inch of plutonium = density x volume = 324,726 grams
It would weigh 1,342 pounds.
Pulverised coal = 38 pounds per cubic foot
9.052 pounds
16 lbs
That depends on how much of it you have!One pebble doesn't weigh very much, but a cubic foot of granite weighs 168 pounds! Compare that to water, which weighs about 62 pounds per cubic foot.

175 lbs
It depends what the ash comes from.
1 cubic foot = 28.316847 litres The answer is in volume, the question was asking for weight. Thanks
Slate weighs 160 pounds per cubic foot.
