1 billion = 1,000,000,000 or 10^9 1 trillion = 1000 nillion = 1,000,000,000,000 or 10^12 14 trillion = 14,000,000,000,000 or 14 x 10^12
If the blocks are 12 inches x 12 inches then each block measures 1 square foot. An area of 14 feet x 14 feet has a surface area of 196 square feet, so it would require 196 of the 12" x 12" blocks to cover it.
