Answer:
D=0.33333333333333 g/cm^3 or D = 0.33333333333333 grams per cubic cm

Explanation:

To find the density of the object we must use the density formula
D=(m)/(v).

We already have our mass so we have to find the volume of the object using the formula
V=a^3, where a is the length or side of the object.


V=3^3 We multiply 3 by itself 3 times


V=27cm^3

So our volume is 27 and since our mass is 9 we can solve for the density.


D=(9g)/(27cm^3)


D=0.33333333333333g/cm^3

So the density would be 0.33333333333333 grams per cubic cm

Explanation:

Volume of the cube = Side length³ = 3 cm × 3 cm ×3 cm = 27 cubic cm

Now, using the formula:

Density = Mass / Volume

Density = 9 grams / 27 cubic cm

Density = 0.333 grams/cm³

So, the density of the cube is approximately 0.333 grams per cubic centimeter.
