Earth to the Sun. Area A billion square inches could make a square about one half mile on a side. A bolt of finely woven 1000-TC bed sheet linen with a billion thread crossings would have an area of , comparable to the floor area of a motel unit. Volume There are one billion cubic millimetres in a cubic metre, and a billion cubic metres in a cubic kilometre. A billion grains of table salt or granulated sugar would occupy a volume of about . A billion cubic inches would be a volume comparable to a large commercial building slightly larger than a typical supermarket. Weight Any object that weighs would weigh about as much as 5,525 empty Boeing 747-400s. A cube of iron that weighs would be on each side. Products As of July 2016, Apple has sold one billion iPhones. This makes the iPhone one of the most successful product lines in history, surpassing the PlayStation and the Rubik's Cube. As of July 2016, Facebook has 1.71 billion users. Nature A small mountain, slightly larger than Stone Mountain in Georgia, United States, would weigh (have a mass of) a billion tons. There are billions of worker ants in the largest ant colony in the world, which covers almost of the Mediterranean coast. In 1804, the world population was one billion. Count A is a cube; B consists of 1000 cubes the size of cube A, C consists of 1000 cubes the size of cube B; and D consists of 1000 cubes the size of cube C. Thus there are A-sized cubes in C; and 1,000,000,000 A-sized cubes in D. Selected 10-digit numbers (1,000,000,001–9,999,999,999) 1,000,000,001 to 1,999,999,999 1,000,000,007 = smallest prime number with 10 digits. 1,000,006,281 = smallest triangular number with 10 digits and the 44,721st triangular number. 1,000,014,129 = 316232, the smallest ten-digit square. 1,003,003,001 = 10013, palindromic cube 1,021,147,343 = 10073 1,023,456,789 = smallest integer containing all digits 1,024,192,512 = 10083 1,026,753,849 = 320432, the smallest pandigital square in base 10. 1,069,863,695 = number of square (0,1)-matrices without zero rows and with exactly 9 entries equal to 1 1,073,741,824 = 327682 = 10243 = 645 = 326 = 810 = 415 = 230 1,073,742,724 = Leyland number 1,073,792,449 = Leyland number 1,093,104,961 = number of (unordered, unlabeled) rooted trimmed trees with 28 nodes 1,104,891,746 = number of partially ordered set with 12 unlabeled elements 1,111,111,111 = repunit,
