What is the mass of a cube of aluminum that is 4.0 cm on each edge? The density of aluminum is 2.7 g/cm3.

mass = volume x density

density is given
volume = 4 cm*4 cm*4 cm = ? cm^3.

64

To find the mass of the aluminum cube, we can use the formula:

Mass = Density x Volume

First, let's calculate the volume of the cube. The volume of a cube is given by the formula:

Volume = (side length)^3

In this case, the side length of the cube is 4.0 cm.

Volume = (4.0 cm)^3

Volume = 64 cm^3

Now, we can calculate the mass using the given density of aluminum, which is 2.7 g/cm^3.

Mass = 2.7 g/cm^3 x 64 cm^3

Mass = 172.8 g

Therefore, the mass of the aluminum cube is 172.8 grams.

To find the mass of the aluminum cube, we can use the formula:

Mass = Density x Volume

First, let's calculate the volume of the cube. The volume of a cube is given by the formula:

Volume = Edge length^3

In this case, the edge length is 4.0 cm, so the calculation would be:

Volume = 4.0 cm x 4.0 cm x 4.0 cm = 64.0 cm^3

Now, we know that the density of aluminum is 2.7 g/cm^3. So, we can substitute the values into the formula:

Mass = 2.7 g/cm^3 x 64.0 cm^3 = 172.8 g

Therefore, the mass of the aluminum cube is 172.8 grams.
