How many pieces are on a scrabble board?
There are 100 letter scrabble tiles in the game set, and the grid is 15x15 (for normal scrabble, super scrabble is 21x21).
If you multiply two odd numbers what type of number do you get?
you get an odd number all the time e.g. 1x1= 1 57x3= 171 21x21= 441 47x35= 1645
How do you calculate how much space you'll need for a wedding tent?
take the amount of space you have and reduce by about 4 feet. So if you have a 25x25 space for a tent you will be able to get a 20x20 since they don't make a 21x21 tent. This will provide room for stakes to be driven into the ground.
How many square numbers are therE between 1 and 500?

What are all the multiples of 21 up to 500?
The multiples of 21 up to 500 are as follows: 21x1=21 21x2=42 21x3=63 21x4=84 21x5=105 21x6=126 21x7=147 21x8=168 21x9=189 21x10=210 21x11=231 21x12=252 21x13=273 21x14=294 21x15=315 21x16=336 21x17=357 21x18=378 21x19=399 21x20=420 21x21=441 21x22=462 21x23=483 21x24=504

How much fabric are you supposed to use?
In order to know how much fabric is needed to make a quilt, you need to look at the instructions for the quilt that you are making. In order to make a quilt, you have to have instructions. They will tell you how much fabric you will need on the packages.
How much fabric to make a 16 x 16 throw pillow?
It depends on how thick the pillow is, but 2/3 yard should be plenty. For an average thickness pillow the rule of thumb is to add 2-3 inches to each side, and then use a 1/2 inch seam allowance. So, sew two 20x20 or 21x21 squares together. Keep in mind that when in doubt, it is easiest to make the pillow cover big and then make it smaller by taking in the sides if needed.
How can millions transistors be in a single processor?
Thanks to the wonderful technology we now posess, a single transistor can be constructed out of two thin layers of material (P-doped and N-doped), and can be very, very small - as small as a few atoms, as some researchers have proved not too long ago! Therefore it is easy to put many such small transistors - in layers - on a small chip - the processor. Many of these, in mass production, have these transistors constructed on the micron scale (typically around 15 microns). If a transistor is 15 microns wide, you can put 66 of them in a milimeter, on just one layer, many of which construct a single processor die. It is now typical to have not millions, but billions of transistors on a single CPU!Think about it: if you can put 66 transistors in a 15x15 micron area, you can fit about 11 108 889 (11 million) of them in a 5x5cm chip - and that's just one layer about a micron thick? Assuming the die itself is 4x4cm and is 3mm thick, each layer is 2 microns thick, and each transistor takes a 21x21 microns of space on a layer --- on such a processor die you would fit 5 442 175 500 - 5 and a half billion transistors.Of course, these transistors switch very small currents - very small indeed! Your typical, run-of-the-mill discrete transistor can handle much larger currents, and its bulky body is designed to dissipate the heat generated in the process, as nothing else will cool it down. Processors usually have designated cooling methods (like radiators and fans) - without one, the temperature within one rises to "boiling" within seconds.
