2. cement has a density of 3.0 g/cm3. you must pour a cement walkway with the
measurements: 6 meters long by 1 meter wide by 10 centimeters thick. what is
the mass of this walkway? (be careful notice that you will have to make some
metric conversions! ) [show your work! ]

For this case we have to by definition:

Where:

d: It is the density

M: It's the mass

V: It is the volume

According to the data we have to:

On the other hand we have that 1 meter is equivalent to 100 centimeters. Thus the measurements of the walkway are:

600 cm long, 100 cm wide and 10 cm thick. Looking for the volume we have:

According to the formula we have:

Thus, the mass of the walkway is 1,800,000g

1,800,000g

your answer would be 10x - 1
