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?
Options
A) 48	B) 99	C) 266	D) 28	E) 17
Explanation:   If you double the sides of a cube, the ratio of the surface areas of the old and new cubes will be 1: 4. The ratio of the volumes of the old and new cubes will be 1: 8.   Weight is proportional to volume. So, If the first weighs 6 pounds, the second weighs 6x8 pounds =48.   48nswer: 48) 48
