Answer:
[tex]3 \sqrt{3} \: (2 \sqrt{2} + 2 \sqrt{3} ) \\ (3 \sqrt{3} \times 2 \sqrt{2}) + (3 \sqrt{3} \times 2 \sqrt{3} ) \\ \\ 6 (\sqrt{3} \times \sqrt{2} )+ 6 ( \sqrt{3} \times \sqrt{3} ) \\ \\ 6 \sqrt{6} + 6(3) \\ \\ = 6 \sqrt{6} + 18 \\ \\ 6(2.449) + 18 \\ \\ 14.694 + 18 \\ \\ = 32.694[/tex]
I hope I helped you^_^
