There are many differences between cu ft. and lbs. These are all very different ways to measure very different things.
0.2836 lbs./Cu. In. OR 460 lbs. / cu. ft.
== No!!== 1.5 cu ft of what?! A pound is a unit of weight. A cubic foot is a unit of volume. 1.5 cu ft of concrete weighs much more than 1.5 cu ft of air.
lets see:1 US gallon = 0.133680556 cubic feetconcrete weights about 150 lbs / cu ft.145 lbs unreinforced.145 x .133680556 = 19.38368062 lbs
21 ft*10 ft*2 in = 21 ft*10 ft * (1/6) ft = 21*10/6 cu ft = 35 cu ft.
It is 25 Cu. Ft. I have the same model
6"by 6"by" 6"= .5 Cu Ft
The answer is specific to the product in the cu ft. A cu ft of water will be different than that of a cu ft of feathers ETC.
0.2836 lbs./Cu. In. OR 460 lbs. / cu. ft.
48 foot trailer: 3000 cu. ft. or 30,000 lbs 53 foot trailer: 3400 cu. ft. or 34,000 lbs.
Yes
search engine says that: 1 ft^3 = 62.42797 lbs; so, 4.3 cubic ft = 268.440271 lbs; forgive me.
35 to 40 lbs per cu ft
== No!!== 1.5 cu ft of what?! A pound is a unit of weight. A cubic foot is a unit of volume. 1.5 cu ft of concrete weighs much more than 1.5 cu ft of air.
The actual difference is exactly 1.0 cubic foot. That's a volume of space that's filled by about 71/2 gallons .
This question cannot be answered sensibly. A cu ft is a measure of volume, with dimensions [L3]. A pound is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information. As a simple mental exercise consider a cu ft of air and a cu ft of water. They will have very different weights.
The difference in volume is 0.2 cubic feet. That's the same thing as 345.6 cubic inches.Without more information, there's no way to tell anything about the shapes involved.
compare two drums 1 23.5 " diameter by 16 " high = 4.01 cu ft 2 24.4 " diameter by 16' high = 4.32 cu ft
