You are given a 10x10x10 cube composed of one thousand 1x1x1 "mini-cubes" glued together. If the outer most layer falls off, how many "mini-cubes" would have fallen off?
Hint: Think about one face at a time.
You started with 10x10x10 = 1000 cubes. The outer layer falling off will leave you with 8x8x8 = 512 cubes, which means 488 cubes have fallen off.
Using the BrainTracker grid below, how many words can you find? Each word must contain the central H and no letter can be used twice. The letters do not have to be connected. Proper nouns are not allowed, however, plurals are. Can you find the nine letter word?
