Multiply your width x depth to get square footage needed- 13 feet times 13 feet =169 pavers that are 12 inches by 12 inches. This assumes that the pavers will be placed right next to each other, with no grout or sand in between. if you plan to leave space for sand or grout, for instance, one row of 12 pavers with 1 inch between each paver will be 12 feet, 11 inches wide. If you go with this plan, you need 12 x12 pavers, or 144.
As with any math problem you will need to convert either side of the equation to the same units. in this case it is easier to convert to square inches. As each foot contains 12 inches then each side of your 10 foot square is 12 inches times 10 feet which is 120 inches. So each side is 120 inches long. To find the total square inches you just multiply the two sides. 120 X 120 = 14400. So you "patio" is 14400 square inches in size. Your pavers are 16 inches by 16 inches so multiply their two sides and you'll get 16 X 16 = 256 So a paver is 256 Square inches. Now that both the patio and the paver are in the same units you only need to divide the patio (14400) by a Paver (256) and that is 56.25 pavers. Round that up because they usually won't sell you a 1/4 paver. Here is how to make the patio come out right. Measure over from each corner one half the length of each side and place a pin in the ground. Stretch a string fairly tight across from one side pin to the other to create a cross. Place you pavers starting in the center with each of the first four paver's corners aligned with the corners created by the strings cross. continue laying the edges of the pavers along the strings until you reach the point where a paver will not fit in the space left. Carefully cut the last paver in the row to fit that remaining dimension. Repeat this in all directions until you have filled the 10 by 10 space. Be sure to maintain the same spacing between the pavers in all directions. If you do not have the ability to cut your pavers then you should probably follow the directions above only when you reach the point where a paver will not fit in the remaining space. Make that the new size of your patio and that will be about nine and a half feet by nine and a half feet square with 1/2 inch spacing between each 16 by 16 paver and you will need only 49 pavers.
Not counting the space for sand between the blocks, it would take11,520/(area of each block in square inches)blocks.
If your definition of Oceania includes Australia, New Zealand and Papua New Guinea as well as the Pacific Islands, Oceania's land covers 8,536,716 square kilometres. Earth's land covers 148,940,000 square kilometres. Therefore, (8,536,716/148,940,000)x100 = 5.73%. I hope this has helped.
