Prism a is similar to prism b. the volume of prism a is 2080 cm³.   what is the volume of prism b? a.260 cm³ b.520 cm³ c.1040 cm³ d.16,640 cm³will give brainliest answer!

There are two possibilities if no further information is given.
for two similar prisms, if the ratio of sides is a, the ratio of volume is a³
2080/260=8=2³
16640/2080=8=2³
2080/520=4, not a cubic number
2080/1040, not a cubic number
It is either A or D depending on which prism is bigger. 

Hmm i believe it would be c
