Answer: Hello! Here we have a cube, with a mass of 10g and a side length of 2.5cm.
First we want to determine the volume.
The volume of a cube, is equal to his cubic side length, where L is the side length:
So [tex]V = L^{3} = (2.5cm)^{3} = 15.625 cm^{3}[/tex]
So the volume of the cube is 15.625 cubic centimeters.
Now we want to calculate te density of the material, as you know:
[tex]density = \frac{mass}{volume} = \frac{10g}{15.625cm^{3} } = 0.64 g/cm^{3}[/tex]
This means that the density is 0.64 grams per cubic centimeter.
