This question cannot be answered in a sensible way. A cubic foot is a measure of volume, with dimensions [L3]. A kilogram is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions without additional information.
One cubic foot of air will have far less mass than a cubic foot of lead.
How to convert Cubic meter to BTU
1 kg/cubic metre = 77.853 pounds/ cubic foot.
You need to know the density of the aggregate. Typically that will be in Imperial system (pounds per cubic feet) or in SI system (kilograms per cubic metre). Use Volume = Mass/Density to convert to volume in the same system. Then convert from SI to Imperial (or reverse) using 1 cubic metre = 35.315 cu ft or 1 cu ft = 0.02832 cubic metre.
There are 1728 cubic inches in 1 cubic foot. To convert cu ft to cu in, multiply cu ft by 1728 (cu in per co ft).1,728 cubic inches per cubic foot.
To convert cubic metres to cubic feet, multiply by 35.314667 To convert cubic feet to cubic metres, multiply by 0.028316847
To convert mass (kg) to volume (cubic meters), you need to know the density of the substance. Without the density, you cannot accurately convert 400 kg to cubic meters. Density is needed to convert mass to volume.
Divide by its density.
To convert kilograms (kg) to cubic feet (cu ft) for a solid material, you typically need the density of the material in kg/cu ft. The formula to calculate volume in cubic feet (V) for a given weight in kilograms (W) is V = W / (density in kg/cu ft). Note that for different materials the density will vary and will affect the conversion factor.
You'll have to convert it to cubic inches. A cubic foot has 1 ft length, 1 ft width and 1 ft height. There are 12 inches in a foot so... 12 in x 12 in x 12 in = 1728 in^3 or 1728 cubic inches.
You can convert between feet and inches, or between cubic feet and cubic inches. You can not convert between cubic feet and inches.
First, convert the depth to inches by dividing 2 by 12 (0.1667 ft). Next, multiply 31 ft by 21 ft by 0.1667 ft to get cubic feet (108.5 cubic feet). Finally divide 108.5 cubic feet by 27 (the number of cubic feet in a cubic yard) to get your answer (4.02 cubic yards). Hope this helps!
To convert 100 kg of 20 mm aggregate to cubic meters, you need to know the density of the aggregate. The density of aggregate can vary, but a commonly used value is around 1.5 tonnes per cubic meter. So, you would divide the weight (100 kg) by the density (1.5 tonnes/m³ = 1500 kg/m³) to get the volume in cubic meters. In this case, 100 kg / 1500 kg/m³ = 0.067 cubic meters.
