The mass of a piece of metal is 1200 g. A measuring cylinder contains 150 cm^3 of water. The volume of the metal is 100cm^3. What is the density of the metal

12g/cm³

Explanation:

Given parameters:

Mass of the metal  = 1200g

Volume of water in the measuring cylinder  = 150cm³

Volume of the metal  = 100cm³

Unknown:

Density of the metal  = ?

Solution:

Density is the mass per unit volume of a substance;

  Density  =

Now insert the parameters and solve;

    Density  =   = 12g/cm³

find the surface area of the sphere to the nearest square unit. use a calculator.
