Answer:

The mass of a lead cube whose side have length 1.5 cm is 40.5 grams

Explanation:

1. Let's review the information given to

1. Let's review the information given tous to answer the question correctly:

1. Let's review the information given tous to answer the question correctly:Mass of the cube made out of lead = 12

= 12grams

Side of the cube = 1 cm

2. What would be the mass of a lead

What would be the mass of a leadcube whose sides have length 1.5 cm?

What would be the mass of a leadcube whose sides have length 1.5 cm?For answering the question, let's

What would be the mass of a leadcube whose sides have length 1.5 cm?For answering the question, let'scalculate the volume of the cube and

What would be the mass of a leadcube whose sides have length 1.5 cm?For answering the question, let'scalculate the volume of the cube andthen its density, this way:

Volume = Height* Width * Length

Volume=1*1*1

Volume =1 cm

Let's recall the formula of the density:

Density Mass/Volume, therefore:

Density of the lead = 12/1= 12 gr/cm

Now, let's calculate the volume of the

Now, let's calculate the volume of thesecond cube:

Volume = Height Width Length

Volume = Height Width LengthVolume 1.5 * 1.5 1.5

Volume = Height Width LengthVolume 1.5 * 1.5 1.5Volume =3.375 cm3

Finally, let's calculate the mass, using

Finally, let's calculate the mass, usingthe density of the lead we already

Finally, let's calculate the mass, usingthe density of the lead we alreadyknow:

Density = Mass/Volume

12 Mass/3.375

12 Mass/3.375Mass 12 *3.375

12 Mass/3.375Mass 12 *3.375Mass = 40.5 gramss
