I answered a medium-difficulty-SAT-questions and got 24, but that is wrong; why? A cubical block of metal weighs 6 pounds. How much will another cube of the same metal weigh if its sides are twice as long?

OpenStudy (anonymous):

You have a cube so

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

if the sides are twice as long the volume will be 2^3 times as big

OpenStudy (anonymous):

so its 8 times the weight of the smaller cube
