All-purpose flour weighs approximately 130 grams per cup.
1 cu ft = 119.7 cups, so 1 cu ft of flour weighs approximately 15.5 kg, or 34.3 pounds.
144 lbs per cubic foot if I remember what my dad told me
400kg or there abouts
450
It would weigh 1,342 pounds.
An 80-pound bag of premixed cement = .667 cubic feet, or 2/3 of a cubic foot, of concrete. A 60-pound bag of premixed cement = .5 cubic feet, or 1/2 of a cubic foot, of concrete.
9.052 pounds
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.
Answer #1:9 cubic yards cement weight nearly 1260 lbs=============================Answer #2:Answer #1 is a very intriguing one. It says that 9 cubic yards (9 x 27 cubic feet)of cement weighs nearly 1,260 pounds. If so, then each cubic foot would weighnearly 5.2 pounds, which corresponds to nearly 8.3% of the density of water.So cement would float quite high in water. Mysteriously, it doesn't.I found one online conversion reference that says that1 cubic foot of Portland cement weighs 94.02 pounds.(94.02 pounds/cubic foot) x (9 cubic yards) x (27 cubic foot/cubic yard) = 22,847 pounds(rounded)Somehow, that sounds more like it.Also, if the question actually meant 'concrete, limestone with Portland cement"instead of 'cement', then the weight is nearly 60% greater than that.
That depends on the type of cement used, and the measurement base (Metric or Imperial (inches)). Also cubic measurements are made with 3 base numbers, not 2 so your cubic feet of the barrel is not known, so your weight cannot be estimated. Cement weighs in between 90 and 135 pounds per cubic foot - although special mixes can weigh a lot more or less.

It depends what the ash comes from.
Redwood weighs around 28 to 31 pounds per cubic foot, making it a relatively lightweight wood compared to others, which can weigh significantly more per cubic foot.
