Consider two cubes, one of aluminum and one of copper. If each cube measures 6 cm along an edge, calculate the mass of each cube mCu =
Answers
Answer:
I guess you this is the answer
Explanation:
Like a square, all sides of a cube by definition have the same value, so once you know the length of one edge, you also know the length of the other edges. Using this idea, you can calculate the mass of a cube with the formula for Density = mass ÷ volume.
Review the formula for density: Density = mass ÷ volume. If you solve this equation for mass, it becomes: mass = density x volume.
Read or review the problem carefully to pick out the details given. The problem will generally state the density (as kilograms per meter cubed, or kg/m3) and some factor of volume (length, width or height).
Calculate the volume of the cube if it is not given using the formula, volume = length x width x height. For example, a cube with a height of 3 meters has a volume of 27 cubic meters (3 m x 3 m x 3 m = 27 m3).
Plug the numbers of the problem into the equation, mass = density x volume. For example, mass = 100 kg/m3 x 27 m3 = 2700 kg. The unit for density (kg/m3) and the units for volume (m3) cancel out to equal the unit for mass (kg).
