m3
m3 + 1 = (m + 1)(m2 - m + 1)
The GCF of m2, m3, and m4 is m2.
M6 - 81 = M6 - 92 = (M3 - 9)(M3 + 9) [difference of two squares]

Between 830kg/m3 to 1650kg/m3 Cement (finely ground gray or white powder used to bind concrete mixtures) weighs between 830 kg/m3 and 1650 kg/m3 (52 lbs/ft3 and 103 lbs/ft3) depending on its handling. The weight of cement that has been pneumatically loaded into a cement silo may be as low as 830 kg/m3 (52 lbs/ft3), while cement that has been stored for a period of time exposed to vibration may be as heavy as 1650 kg/m3 (103 lbs/ft3). It is standard practice to consider a 94 lb bag of cement to be one cubic foot when freshly packed. Two 500-mL beakers were used for 500 grams of dry powdered cement. Cement was simply poured into beaker No 1. Cement was slightly vibrated-imitating consolidation during transport or packing while stored in a silo, into Beaker No 2. An approximately 20% difference in bulk volume was found. This demonstrates the need to measure cement by mass instead of volume for batching concrete.
1400 kg/m3
please define your question again. Different concrete mixes have different cement consumptions depending upon their design mix.

The volume is(1000)/(density of cement in kg/m3) cubic meters.
The cement density is used in the calculation of the total aggregate content and of the concrete density.Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. There are many different kinds of concrete, many of which are much lighter. Cement is the liquid (or paste like) form, and tends to be much heavier than when it has cured into concrete. "Cement" is not concrete, but can be used to make concrete by mixing with sand, stone and water. The density of cement is about 3120kg/m3.

The density of Portland cement is 1.44 ton/m3.

To calculate the quantities of cement, sand, and gravel in 1 cubic meter of concrete with a ratio of 1:2:4, you first need to determine the total parts of the mixture, which is 1+2+4=7 parts. Then, divide 1 cubic meter by the total parts (1/7, 2/7, 4/7) to get the volume of each ingredient. So, in 1 cubic meter of concrete, you would have 0.143 cubic meters of cement, 0.286 cubic meters of sand, and 0.571 cubic meters of gravel.
A used BMW M3 can range between $13,000 and $60,000, depending on the year of the car. For example, a 2003 BMW M3 costs about $12,999 whereas a 2011 BMW M3 costs about $60,000.
