The volume of the diamond will be equal to V=202.56 cm³
<h3>What is volume?</h3>
The Volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space.
The Mass is given as= 712.04 grams
The density is given as =3.51 gram per cm cube
So we know that the density is given by the formula:

V=202.56 cm³
Hence the volume of the diamond will be equal to

hope this helped and hope its correct tell me it its not !!!
Step-by-step explanation:
Given
(2x + 3 )² - (2x + 3) (x - 5)
= 4x² + 6x + 9 - ( 2x (x - 5) + 3(x - 5 ))
= 4x² + 6x + 9 - ( 2x² - 10x + 3x - 15 )
= 4x² + 6x + 9 - 2x² + 10x - 3x + 15
= 2x² + 13x + 24
Hope it will help :)
