Many experts advise to check your urine for ketones when your blood glucose is more than 240 mg/dl. When you are ill (when you have a cold or the flu, for example), check for ketones every 4 to 6 hours. And check every 4 to 6 hours when your blood glucose is more than 240 mg/dl.
There are calculators that estimate, but you need to determine the pavers you want, because the Sq. Ft. differs from one paver type to another, depending on thickness and paver dimensions. Most brick yards will tell you the Sq Ft when you find a suitable paver. http://www.whiteblockcompany.com/pavers-...

Including materials, a general estimate for installing interlocking concrete pavers is between $15 and $20 per square foot. More intricate patterns may increase the cost closer to $30 per square foot. Interlocking brick paver costs are typically similar to those of the concrete system, but materials costs may be a bit higher depending on the size of the brick pavers you choose. The smaller the paver, the higher the materials cost.
