A block of ice measuring 1 foot by 1 foot at the base is placed in a 2 foot by 3 foot aquarium. Water is then added to a level of 9 inches. Once the ice melts, the level of the water remains at 9 inches. How tall was the block of ice?
A 2 foot by 3 foot aquarium is filled with 9 inches of water. A 1 foot ice cube is placed in the corner. How much will the water rise once the ice melts?

If no row, column or diaganol can have more than five pieces on it, what is the maximum number of squares that can be occupied on a chess board?
If you want to show a solution, use “_” and “X” for empty an occupied. Whatever you use, I’ll make sure it aligns (within 24 hours of your posting).
An oil well being drilled in flat prairie country struck pay
sand at an under ground spot exactly 21,000 feet from one corner of a rectangular plot of farmland, 18,000 feet from the opposite corner, and 6000 feet from a third corner.
How far is the underground spot from the fourth corner ?

Two flying raindeer leave the North Pole. One flies South at 20 mph, the other flies to the right at 50 mph. How many hours does it take for them to be 210 miles apart?
Back in 2010, a question was about this: ” f * ABCD = DCBA “.
I easily found these… 4 * 2178 = 8712 and 9 * 1089 = 9801
I also found a pair for five digit : ” f * ABCDE = EDCBA “.
But it seems that for six digits, there was no solution.
Can you find a solution for five digits? And if so, what about six digits?
