A piece of wood has a mass of 40 g and volume of 60 cm3. What is the density of the wood?
100 g/cm3
2400 g/cm3
.67 g/cm3
1.5 g/cm3
To find the density of the wood, you need to divide the mass of the wood by its volume. The formula for density is:
Density = Mass / Volume
Given that the mass of the wood is 40 g and the volume is 60 cm³, you can substitute these values into the formula:
Density = 40 g / 60 cm³
Calculating the division:
Density = 0.67 g/cm³
Therefore, the density of the wood is 0.67 g/cm³. So the correct answer is .67 g/cm³.
density = mass / volume
hint ... the density of water is 1 g/cm^3
... most wood floats , so the density is probably less than water
