Answer:
D = 0.925g/cm³
Explanation:
Use the formula to calculate density.
[tex]D = \frac{m}{V}[/tex] 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.
