Question 1136623
.
<pre>
". . . dilated . . . " means "all measurements are increased by the factor of {{{6/5}}} ".


Then the volume is increased by the factor of  {{{(6/5)^3}}} = {{{216/125}}}.


The volume of the dilated prism is  {{{(5*10)*(6/5)^3}}} = {{{(5*10)*(216/125)}}} = 86.4 cubic feet.

Ignore the answer and the solution by @Saffana, since they both are incorrect.
