1. A cylindrical barrel with a radius of 9cm is about half-filled with water. A solid concrete block is dropped into the barrel. The level of the water rises 1cm. What is the volume of the block?

2. Suppose a cat gives birth to 4 kittens. Sandy says that since each kitten is equally likely to be a male or female, it most likely each litter consists of 2 males and 2 females. Is Sandy right? Why?

3. A box holds 200 marbles. ANother box is twice as long, twice as wide, and twice as high. Estimate how many marbles will be held.
