what is the density of aluminum if you have a piece of aluminum that is 10.5cm x 10.5cm x 0.1cm and has a mass of 29.8 grams?

2.7g/cm³

Explanation:

Given parameters:

Dimension of the aluminum  = 10.5cm x 10.5cm x 0.1cm

Mass of the aluminum  = 29.8g

Unknown:

Density  = ?

Solution:

Density of a substance is its mass per unit volume;

  Mathematically;

       Density  =

Volume of the aluminum  = 10.5cm x 10.5cm x 0.1cm = 11.025cm³

  So, insert the parameters and solve;

  Density  =   = 2.7g/cm³
