Question

A cube has a side length of 3 cm. The mass of the cube is 9 grams. What is the density of the object? Density = Mass / Volume

Answer 1

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

Answer 2

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.
