what's the density of a cube of an unknown substance if mass is 45.2g and the side of a cube is 3.2cm?

volume of cube is 3.2 x 3.2 x 3.2 = ?cc

Then density = mass/volume.

To find the density of a cube, you need to divide its mass by its volume.

Step 1: Calculate the volume of the cube
The volume of a cube is determined by raising the length of a side to the power of 3. In this case, the side length is 3.2 cm.

Volume = (side length)^3
Volume = (3.2 cm)^3
Volume = 32.768 cm³

Step 2: Calculate the density
The formula for density is:

Density = Mass / Volume

Given that the mass is 45.2 g and the volume is 32.768 cm³:

Density = 45.2 g / 32.768 cm³

Step 3: Calculate the final answer
Perform the division to find the density:

Density = 1.38 g/cm³

Therefore, the density of the cube of the unknown substance is 1.38 g/cm³.
