The mass should be 75.71 grams
To find density is D = M / V
So you would have to multiply the volume by the density
33/20 as well as 1 and 13/20. First you look it up in the internet aka Google.

Determine the density of the wood
First, we calculate the volume of the wood.

Substitute values for Length, Width and Height


The density is:


<em> --- approximated</em>
Well, the answer would be square root of 3 over 2 because of the unit circle. So, the answer choice should be which ever one involved square root 3 over 2
