To determine how many 12-inch blocks are needed to make a 4-foot circle, we first need to convert all measurements to the same unit. Since there are 12 inches in a foot, a 4-foot circle is equivalent to 48 inches in diameter. The circumference of a circle can be calculated using the formula C = πd, where d is the diameter. For a 48-inch diameter circle, the circumference would be 48π inches. To find out how many 12-inch blocks are needed to approximate this circumference, we would divide 48π by 12 to get the number of blocks required.
This is a non-trivial question because the curvature of the circle means that in some cases a whole block is required to cover only a tiny part of the circle.
Covering a circle with a diameter of 4 feet would require 16 blocks measuring 12 inch * 12 inch. This is despite the fact that the total area of the blocks is more than 27% larger than the area of the circle. This was proved by Maurizio Morandi in May 2009.
If the 12 inch blocks are blocks comprising 12 blocks of 1 sq inch each, which can be configured as 2*6 rectangles, or 2+3+3+2+2 shapes, the the problem becomes hugely complex.

How many revolutions of a 12-inch wheel make 1 mile?
A 12-inch wheel has a diameter of 12 inches, which is 1 foot. The circumference of the wheel is π (pi) times the diameter, or π feet. A mile is 5,280 feet, so the 12-inch wheel must turn 5280/π or about 1,680.676 times.

How many 6 x 6 blocks can be made out of a 4 foot board?
Assumption: 6 x 6 is using inches as the unit (half a foot) and a 4 foot board means 4 square feet of board. Each square foot of board can be cut into four half foot x half foot pieces. Therefore, the 4 foot board would be able to make 16 half foot x half foot (6 inch x 6 inch) blocks.

How many 5 inch quilt squares will you need to make a king size quilt measureing 120x124 with no border?
ACK ! 120 divided by 4.5 ( allowing for quarter inch seams ) = 26 blocks wide. 124 divided by 4.5 ( allowing for quarter inch seams ) -= 27 blocks deep. ( These are rounded numbers, since 27 blocks wide, is actually 26.66666 and 27.5555 blocks. ) For a total of 702 blocks. If you prefer, make 24 blocks wide and 26 blocks deep, and make up the difference in finished size with your border. 624 blocks.

How many 9 inch long blocks of wood can be cut from a board that is 7.5 feet long?
A board that is 7.5 feet long is 7.5 x 12 = 90 inches long. You can (mathematically) make 10 blocks 9 inches long from 90 inches of material, but only if the blade of your saw has a width (kerf) of zero. In the real world, you'll get 8 blocks and a good bit of change sawing 9 inch blocks off a 7.5 foot board. For a saw kerf of 0.125 inches (1/8th of an inch), You'll have lost 1 inch in your cuts, and you'll get 8 of the 9-inch pieces with your leftover piece being 8 inches long.
