There is a popular myth about the man who invented chess. The local ruler was so pleased with the invention that he offered the inventor a great reward in gold. The inventor suggested an alternative reward: he would get one grain of wheat on the first square of the chess board, two grains on the second square, fourth on the third, eight on the fourth, etc., doubling the number of grains each time. The ruler saw that this must be a much better deal for him, and he accepted. The board has 64 squares.
1. How many total grains of wheat did the ruler have to pay the inventor?
The answer is 1+ 2+4+8+...+2^63. Use a for loop to calculate and display the value.
2. A wheat grain weighs approximately 50mg. How much did the wheat weigh?
3. Include text boxes to prompt for dimensions of a swimming pool (height, width, and length). Determine how many such swimming pools would be needed to store quantity of wheat found in part 2.
Assume that the approximate volume of an average grain of wheat is 20 mm3.
The number of swimming pools needed is calculated using the following formula:
(Volume of a grain of wheat) *(Amount of wheat)
Number of swimming pools needed = --------------------------------------------------------------
I have the basic stuff set up but I dont know how to set up the volume part of it.

When the user clicks on a state they are taken to the bulletins page for that state.
Create the page the user see's when they get to this bulletin page. Make sure it is in the style of this theme.
You can mock up your own data etc.
Basic fields to use would be: bulletin title, a trunucated version of the body, a date, a username (posted by: x), view count, and reply count.
You can think of it as a forum index.
Bulletins can be one of two types: an event, or an announcement. Find a way to distinguish between an event and an announcement. Events should also have number of attendies as well as views and replies.

I am trying to make a game that has 8 shells moving from left and the user presses a button to stop them. On the rows above 1 less shell each time and the user must line up the shells on top of the previous ones or they will lose the game and have to start over. The speed should increase as there becomes less and less shells.
