Question

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

Answer 1

D. A cube measures 3 cm on each side and has a mass of 25 grams. What’s the density

Answer 2

D = 0.925g/cm³

Step-by-step explanation:

Use the formula to calculate density.

`D = (m)/(V)` 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.
