Before electronic calculators, converting square varas (at 1 vara = 32.8748 inches) to acres was a tedious job. But if 1 vara = 33 1/3 inches, 3 varas are exactly 100 inches, 36 varas are exactly 100 feet, and 108 varas are exactly 100 yards. An easy division and some shuffling of the decimal point do the job.
One square foot is one foot wide by one foo â¦ t tall (1 ft x 1 ft = 1 sq ft). Actually you can't measure how many feet are in a square foot since one is distance and the other area. for example, a rectangle that is 0.25ft by 4 ft would have a area of one square foot and a perimeter of 8.5 feet.ne cubic yard of decomposed granite will cover one-hundred-eight (108) square feet in a three-(3)-inch layer. But we need to double-check our work. So taking the number one-hundred-eight (108), we will divide it by four to find out how many cubic feet of granite there are, and we reach the number twenty-seven (27).
