Question

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?​

Answer 1

2.7g/cm³

Step-by-step 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
