Area

15 acres = 60702.85 sq metres (to 2 dp)

10' x 11.5' = 115 square feet

4.123" X 4.123" =17sq"

acre is american, kilometer is English, you need to convert your kilometers to feet, 1 kilometer = 3 280.8399 feet

1 square foot = approx 0.093 square metres.

10 x 8 sqft...

A foot is 0.3048 meters. So that would give you 9,429 feet.

An Acre antshrike is a bird of the antbird family, Latin name Thamnophilus divisorius.

The area of Bouconvillers is 4,790,000.0 square meters.

1800 sq ft = 200 sq yd.

There are 9 square feet in one square yard.

Therefore, 110 square yards is equal to 110 x 9 = 990 square feet.

12' * 8' = 96 sq ft = 8.92 sq metres

1.1583064756273E-10 mi2

Depends on the size of the squares.

875.11 ft2

236,095.2 square feet.

60 x 30 feet? 1800 sq feet.

1385

43,560 are.

One tile that is 12 ft by 12 ft will be more than enough.

6 yards x 4 yards = 24 yards2

You can't convert square feet to ground since these terms are not totally related to each other. "square feet" measures the area of the object while "ground" is surface of the Earth.

None.

An acre is a measure of area, whereas a mile is a measure of distance. The two measure different things and, according to the basic principles of dimensional analysis, conversion from one to the other is not valid.

To convert from square miles to sq kms, multiply by 2.59.

Personally, I'd say a trick question... Square yards would only be relevant to a flat area, wheras from the details you've given, you're after cubic yards? In which case it would be 740.740740740...... (recurring) cubic yards
