Concrete has a density of 2.30 grams per centimeter cubed. What is the
mass of a concrete block in kilograms that is 1000.Ocm x 1000.Ocm x 15.0
cm? *

Answer 1

Step-by-step explanation:

density=2.30 g/cm^3

volume=1000.0 cm*1000.0 cm*15.0 cm=15000000

now we know that

d= m/v

therefore

m=d*v

m=2.30*15000000

m=34500000 g

now we have to convert grams into kg

1kg=1000 g

34500000 g=34500000/1000

34500000 g=34500 kg
