The question cannot be answered sensibly.
25000 m3 is a measure of volume, not of mass. That volume of lead, for example, will have quite a different mass to the same volume of air. In addition to the volume, you need to know the density of the substance involved.
27262.8 m3
Density (kg/m3) = mass(kg)/volume(m3)= 0.386/20x10-3 = 19.333333....kg/m3
The least possible number that can be rounded off to 25000 is 24995.
density= mass/volume (mass divided by volume) mass is usually in grams(g) or kilograms(kg) volume is in meters cubed or m3 so density would be either g/m3 or kg/m3
density = mass / volume density = 0.250 kg / (0.05 m)3 density = 0.250 kg / 0.000125 m3 density = 2000 kg/m3 (For comparison, pure water's density is about 1000 kg/m3)

Find the density of a material that has a mass of 2 kg and a volume of 5 m3.
To calculate the density, you need to divide the mass by the volume.
The mass of an object is equal to the object's density multiplied by the volume (size) mass (kg) = density (kg/m3) x volume (m3)
The mass of an object is equal to the object's density multiplied by the volume (size) mass (kg) = density (kg/m3) x volume (m3)
I calculate in SI-units. Use appropriate units for your own use. Density is mass pr. volume, like: 0.2 kg / m3 so when you have 10 m3 you just multiply the two numbers: 0.2 kg/m3 time 10 m3 = 2 kg Note that the cubic meter (m3) is shortened out by it self. So you end up with the mass alone.
Anywhere between 0.08 tonnes and 0.125 tonnes. Depending upon the type of asphalt, and its actual make up, the density of asphalt can vary between 1.6 tonnes/m3 and 2.5 tonnes/m3 1000 mm = 1 m mass = volume x density volume = 1 m2 x 50 mm = 1 m2 x 50 ÷ 1000 m = 0.05 m3 The mass can vary between: lightest: mass = 0.05 m3 x 1.6 tonnes/m3 = 0.08 tonnes heaviest: mass = 0.05 m3 x 2.5 tonnes/m3 = 0.125 tonnes
1000Kg/m3
All matter has mass. Air is made of matter (oxygen, nitrogen, argon, etc.) and has mass. The mass of air at standard conditions is 1.229 kg/m3
