One cm^3 is equal to one ml. The problem is simple after you know that.

The answer is 1.75g/cm^3.

You may want to be careful of your label. Some teachers prefer “cubic cm” to “cm^3”, and mat count one or the other wrong.

If you wanted to show the work, it would look something like this:

1.75g/1ml X 1ml/1cm^3 = 1.75g/cm^3

The other problem that you posted makes very little sense. “1.75 g/ml=(21.34cm)(213.34 cm)(h)” is an impossibility. You can use 1.75 g/ml to find out the weight of the object if you know the height (h), or the height if you know the weight of the object. 1.75g/ml is the density.

Edit: The number of people that answered this incorrectly shows that humanity has no hope.

You cannot convert a concentration (grams of something per unit of volume) to a linear value, such as distance.

Better look at that homework question again, sweetie.

Looking at the “additional information,” it still does not work.

Why not just write out what your homework question was and let us show you how to solve it. You have done something wrong setting up the question.
