(60,000 sq ft) / (43,560 sq ft / acre) = 1.3774 acre (rounded)
1 yard = 3 ft 1 ft = 12 inch Go figure !
21 780 sq feet To a greater accuracy than scientifically reasonable Given that only one significant figure is in the question a proper answer would be: 2 * 105 square feet
Four lengths indicate that the figure is a quadrilateral. Unfortunately, quadrilaterals are not rigid so that a set of four lengths can give rise to infinitely many shapes with infinitely many areas. This is on the same principle that a quadrilateral with four equal sides can be a square or a very thin rhombus.
Volume is 30 x 20 x 1/6 ie 100 cu ft. 27 cu ft make one cu yd so 100/27 ie 3.7 cu yds to one significant figure.
There are 2 significant figures in this number.
There are 5128 ft. in one mile.
(60,000 sq ft) / (43,560 sq ft / acre) = 1.3774 acre (rounded)
Falls 20 ft and above is a significant mechanism of injury for adults, and falls from 10 ft and above is considered a significant mechanism of injury for children.
1 yard = 3 ft 1 ft = 12 inch Go figure !
(152 cm/(2.54 cm/in)/(12.0 in/ft) = 4.99 feet, to the justified number of significant digits.
1 ft = 12 inches 7.22 ft = 12 x 7.22 = 86.64 inches, or 86.6 inches, to the justified number of significant digits.
