What is the density of aluminum if you have a piece of aluminum that is 10.5 cm x 10.5 cm * 0.1 cm and has a mass of 29.8 grams? Show all work for full credit.

2.7g/cm³ ( Please give me the brainliest:))

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  =  mass/ volume

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

 So, insert the parameters and solve;

 Density= 29.8/11.025  = 2.7g/cm³
