Answer:
[tex]6a^{3}[/tex]
Step-by-step explanation:This is a very simple question.
We all know that the equation or formula for area is...
A= L*W
So multiply...
[tex]2a^{2} *3a[/tex]= [tex]6a^{3}[/tex]
Since 3a has an exponent power of 1 and you add the exponent power when multiplying...
The result would be... [tex]6a^{3}[/tex].
Hope this helps:)
