The two rectangular prisms are similar.
what is the volume of the larger rectangular prism?

1620 cm³

810 cm³

270cm³

240 cm³

Let
y> width of the base smaller prism
z> height of the smaller prism

we know that

 if the prism are similar 
length side larger prism=factor*length side small prism
then
6=factor*2> factor=6/2> 3

volume small prism=2*y*z
30=2*y*z

volume larger prism=6*(3y)*(3z)> 27*[2*y*z]> 27*[volume small prism]
volume larger prism=3³*volume small prism
volume larger prism=3³*volume small prism> 27*30> 810 cm³

the answer is 810 cm³

Ithink the answer is d i hope it

17 is c. congruent means equal in size
