Ihave no clue how to do this! !

the volumes of two similar prisms are 64ft cubed and 216ft cubed. the surface area of the larger prism is 594 ft squared.

find the surface area of the smaller prism.

It's 176 :) if they are similar, you can divide the larger volume by the smaller volume to find the difference (3.375) next, you take the large prisms surface area and divide by 3.375 to get 176! Also, if it were reversed and you needed the surface area of the larger one, just multiply 64 by 3.375 :)

The answer to your question is b
