The density is

#### Explanation:

The density of an object is calculated as the ratio of its mass and volume:

#d=m/V#

Here the volume is not given, but can be calculated using the given dimension:

#V=a^3#

Now we can calculate the density using the given data:

#V=m/(a^3)#

Now we can put the values:

**Answer: The density is #d=1g/(cm^3)#.**
