1000 kg/ 2 m3 = 500 kg per cubic meter density or 0.5 g/cm3 or approximately half the density of water
Density (kg/m3) = mass (kg)/Volume (m3) So to find the density of the wooden block, the triple beam balanced is used to calculate the mass and the metre rule is used to measure the height, length and width of the wooden block. Then the volume is calculated by multiplying the thee distances obtained from the ruler. Finally the density is calculated using the equation: Density (kg/m3) = mass (kg)/Volume (m3)
1 m = 100 cm. So 1 m3 = 1,000,000 cm3. In this case, you divide by a million.
A BMW M3 can handle any speakers, but you may want to get lightweight polymer ones so you don't weigh down your car. anonymous@oola.com
fear M3 ?

m3
1 g/m3 = 0.001 kg/m3 ⇒ 13.6 g/m3 = 0.0136 kg/m3
Usually such magnets are made out of iron. If that is the case, I would expect its density to be similar to that of iron (approximately 7900 kg/m3).
