The volume of a prism is given by #V = A_(base) xx h#

Explanation:

#36x^5y^9 = (3x^2y xx l) xx4xy^3#

#(36x^5y^9)/(4xy^3) = 3x^2y xx l#

When you divide exponents, you subtract them. However, don't forget you can't combine the x and y exponent terms.

#9x^4y^6 = 3x^2y xx l#

#(9x^4y^6)/(3x^2y) = l#

#3x^2y^5 = l#

The length measures #3x^2y^5#

Hopefully this helps!
