Acube measures 3cm on each side and has a mass of 25 grams what is the density

D = 0.925g/cm³

Explanation:

Use the formula to calculate density.

Density is mass divided by volume.

Density tells you how close together the particles of the cube are.

Find the volume of the cube first. The volume of a cube is V = s³

"s" means the length of one side. The length is 3cm. Substitute the side length into the formula.

V = s³

V = (3cm)³     Apply the exponent to both the number and units. 3³ and cm³

V = 27cm³    This is the volume of the cube

The mass is already given, 25g.

Use mass and volume in the density formula:

D = m/V

D = 25g/27cm³    Divide top by bottom.

D = 0.925g/cm³    This is the density of the cube.

The density is 0.925g/cm³.
