A cube of aluminium measures 3 cm on each side and weighs 81 g what is it density
the answer to this question is that density equals 3 g/cm(cubed)
To find the density of the cube, we need to divide its mass by its volume.
First, let's calculate the volume of the cube. Since all sides of the cube are equal, we can use the formula:
Volume = side length^3
Given that the side length of the cube is 3 cm, we have:
Volume = 3 cm × 3 cm × 3 cm = 27 cm³
Next, we divide the mass of the cube (81 g) by the volume (27 cm³):
Density = Mass / Volume
Density = 81 g / 27 cm³
Therefore, the density of the cube is 3 g/cm³ (grams per cubic centimeter).
Idk I doesnt say the anwser
density = mass/volume
mass = 81 g
volume = 3 cm x 3 cm x 3 cm = 27 cc
You finish. But the density of Al is 2.71. The author of this problem didn't choose good numbers.
