How to convert square price into kilogram price

How to convert square price into kilogram price


Could it be the cubic price?
Divide the cubic price (yuan / m3) by the density (kg / m3) to get the kilogram price (yuan / kg)
Total price (yuan) = total weight (kg) times price (yuan / kg)



How to convert AC-5 cubic meter and ton of fine grained asphalt concrete


The density of AC-5 of different materials is different. However, the corresponding standard of asphalt is given in "highway engineering budget quota" in China, which can be used as a reference
The standard density of sand gravel asphalt concrete is 2.350 g / cm3, and the asphalt aggregate ratio is 6.01%. It can be calculated that the asphalt concrete of AC-5 is 2.35 tons per cubic meter



Who knows the conversion between cubic meter per hour and liter per second


For example, how much l / S is 100 m3 / h converted into
1 cubic meter (M3) = 1000 liters
So 100m3 = 100000 liters
1H = 3600 seconds
So 100m3 / h = 27.78/s



How to convert 530 seconds into minutes and hours?


530 / 60 = seconds 530 / 60 / 60 = hours

The least common multiples of 24 and 36 are 72, the least common multiples of 16 and 12 are 48, the least common multiples of 7 and 36 are 252, 30 and 75, and the least common multiples are 150. Your adoption is my driving force,



Let the sum of odd and even terms be 44 and 33, respectively


Let {an} be 2n + 1, s odd = a1 + a3 + +A2N + 1 = (n + 1) (a1 + A2N + 1) 2 = (n + 1) an + 1, s-even = A2 + A4 + A6 + +A2N = n (A2 + A2N) 2 = Nan + 1, s odd s even = n + 1n = 4433, the solution is n = 3, 2n + 1 = 7, because s odd s even = an + 1 = a, so A4 = s odd s even = 44-33 = 11, so the middle term is 11



Calculate the 2n + 1 power of the third power (2x-y) of (y-2x) divided by the 2n + 2 power of (y-2x) (n is a positive integer)


=The third power of (y-2x) [- (y-2x)] of 2n + 1 divided by 2n + 2 of (y-2x) = - (y-2x) of 2n + 4 divided by 2n + 2 of (y-2x) = - (y-2x) of 2n power - (y-2x) of 4 divided by (y-2x) of 2n power (y-2x) of 2 = - (y-2x) of 2n power divided by (y-2x) of 2n power
