Area

Answer: 53,545 acres = 83.7 mi²

1 square centimeter is 0.0001 square meters. 1 square meter is 10000 square centimeters.

120 cubic feet equals 3398 liters.

There are 5,280 feet in a mile, so 5280×10 so 52,800 sq. ft.

We must assume that the figure is a rectangle. 1 yd = 3 ft. 10 yds x 12 yds = 30 ft x 36 ft = 1080 square ft. 1 square meter = (3.28084)2 square ft 1080 square ft = 1080/(3.28084)2 square meters = 100.34 square meters (rounded)

18.1161 sq meters.

Answer: 65795 mi² = 170,408.27 km²

Somewhere around 1911. Value depends on originality and condition. Perhaps $600-$800 in top condition.

Length times width

71.11 square yards.

Texas has an area of approximately 268,820 square miles. Let's ignore the 2.5% that is water.

1 square mile = 5280^2 square feet = 27878400 square feet

268820 mi2 * 27878400 ft2/mi2 = 7494271488000 ft2

7494271488000 ft2 / 6000000000 people ~= 1249.0 ft2/person

The same calculation taking out 2.5% for water would result in ~= 1217.8 ft2/person

15.7 (correct to one decimal place).

13 * 13 = 169 (ft2)

Then either convert manually, or go to an online ft2/m2 converter.

You need to calculate the area of the base (square), and the area of one triangle, and multiply that by 4.

Mass is an attribute of 3-dimensional objects, not 2-dimensional objects. A square foot of steel, with no thickness, cannot exist. Furthermore, the density of steel, depends on the exact composition of the alloy.

According to Wikipedia, the international acre is exactly 4,046.8564224 square metres, and The U.S. survey acre is approximately 4,046.872 609 874 252 square metres.

90,000 meters squared

61.72 is answer

6,475ft² = 0.149 acres

A metre is a unit of length. A square foot is a unit of area. The two units are therefore incompatible.

To convert square metres to square feet, divide by 0.09290304 (that is, 0.3048 squared). In this instance, rounded to two decimal places, 5 square metres is equal to 5/0.09290304 = 53.82 square feet.

If our hasty calculations are correct, it's very close to 25.
