Answer:

[tex]330\ kg[/tex]

Step-by-step explanation:

Remember that

1 kg=1,000 g

1 m= 100 cm

The volume of the granite countertop in cubic centimeters is equal to

[tex]V=(100)(300)(4)\ cm^{3}[/tex]

The density in kg per cubic centimeter is equal to

[tex]D=2.75(\frac{1}{1,000}) \frac{kg}{cm^{3}}[/tex]

Multiply the density by the volume

[tex]2.75(\frac{1}{1,000})(100)(300)(4)[/tex]

[tex]2.75(120)=330\ kg[/tex]
