A block of wood 3.0 cm on each side has a mass of 27 g. What is the density of this block?
The density of an object is calculated as the ratio of its mass and volume:
Here the volume is not given, but can be calculated using the given dimension:
Now we can calculate the density using the given data:
Now we can put the values:
Answer: The density is
Here we got a cube whose mass is
Would the block of wood float on water?
