The density of aluminum is 2.7/10 kg / m, which means that the physical meaning is to cut off half of the aluminum, and the remaining half of the density is 0 1: The density of aluminum is 2.7/10 kg / m, which means that the physical meaning is to cut off half of the aluminum, and the remaining half of the density is 0 2. Comparing iron and copper blocks with the same mass, we can see that the volume of iron and copper blocks with the same volume is larger 3. The density of oxygen is 1.43 and the density of return water is 1.03/10

1. One square meter aluminum mass is 2.7kg 2.7 * 10 cubic kg / M cubic
2. Aluminum iron
3. G / m3 kg / m3

The density of a cuboid aluminum block is 2.7 × 103 & nbsp; kg / m3. It is divided into two blocks, and the density of each block is ()
A. 5.4×103 kg/m3B. 2.7×103 g/cm3C. 2.7g/cm3D. 1.35×103 kg/m3

Since density is a property of matter and has nothing to do with its mass and volume, if it is divided into two pieces, the density of each piece is 2.7 × 103kg / m3 = 2.7g/cm3
