A piece of oak is cut into a block that is 5 cm long, 130 cm wide, and 15 cm tall. The mass of the oak is 9100 grams. What is the density of the oak?

The density of the oak block is 0.93333g/cm^3 (0.93333 grams per centimeter cubed). This can also be rounded to about 0.93g/cm^3.

To first be able to solve this you need to know the equation for density which is D=M/V. You then need to know the equation for volume, in this case it is just the standard length*width*height formula.

First let’s begin finding the volume so 5*15=75. Next we need to multiply 75 by 130 which is 75*130=9750. We then need to plug in our values for the density formula.

Now that we have our volume and the given mass (9100 gams) we can now plug in the values which will look like D=9100/9750 which will then equal to about 0.93333g/cm^3 (0.93333 grams per centimeter cubed).
