34x20=680
The amount of feet per btu varies according to many factors such as how tall the ceiling is or how many windows there are. In most houses, usually you need about 20 to 22 btu per square foot. So, divide 15000 by these and you get it will heat anywhere from about 680 to 750 square feet.
The square root of 680 is an irrational number and it is about 26.0768 rounded to 4 decimal places
680 of them.
No, 31 miles is actually equal to 163 680 feet (1 mile = 5280 feet)
Answer: 680 yd = 0.386363 miles.
An area 20ft x 34' is 680 square feet. 4 inches is 1/3 of a foot so cubic feet required is 680 x 1/3 = 226.7 cubic feet. There are 3x3x3 = 27 cubic ft in a cubic yard. Therefore cubic yards required = 226.7/27 = 8.4 cubic yards
About 2.23 feet are in 680 millimeters.
34x20=680
There are 30.48 centimetres in one foot. Therefore, 680 centimetres is equal to 680/30.48 = 22.31 feet.
One foot is equal to 0.3048 metres. Therefore, 680 feet is equal to 0.3048 x 680 = 207.264 metres.
There are 6 miles in 31,680 feet
Answer = 20 ft x 34 ft = 680 sq ft
680 feet is 207.264 metres.

approx. 74 yards Sorry, Dabar, but I think you have not accounted for the conversion of cu. feet to cubic yards...my calculations are as follows...... 40 X 17 is equal to 680 cubic FEET of area. You take the 680 and divide by 27 to get the cu. YARDS of concrete. (25.1 cu. yds) Then because you only want the slab 4 inches thick, you multiply by .33 (or 8.25 cu. yards of concrete) Then you allow 10 % for waste or shortage....(make this about a yard...so, 8.25 and one for waste/shortage is equal to 9.25 cu. yards of Concrete for this project)
