If one micrometeorite (a sphere with a diameter of 1.50 x10-6 m) strikes each square meter of the Moon each second, how many years would it take to cover the Moon to a depth of 1.20 m? (Hint: Consider a box on the moon 1.00 m on a side and 1.20 m deep, and find how long it will take to fill the box.)

The Box Problem Take an 8% x 11 sheet of paper and cut out 4 congruent squares (one from each corner) as shown below on the left. This creates a net for an open-topped box (rectangular prism) which can be folded up as shown on the right. We're going to use our box to carry as many M & M's as possible. If the side-length of each cut-out square is 1 inch, then the box created will have dimensions 1...
