12' X15' = 180 sq ft 180 sq ft / 9 = 20 sq yds 20 sq yds X $4.50 = $90.00
54/100, x15 is 8.10. 54-8.10 is 45.90
15X15X.33(4/12 there is 4 inches in a foot therefor 4" is .33 of a foot) equals 74.25 cf of concrete divide by 27 (three demensional object for yards) 2.75 Cubic Yards. if you try to order .75 cubic yards of concrete you will be laughed at, just order 3 cubic yards and make a entrance path. good luck.
375 square feet.
The area of the ceiling is 375 square feet. The area of the floor is also 375 square feet. If we knew how low the floor is below the ceiling, we could also tell you the area of the walls.
240 square feet
It is 4 times 15 = 60 square feet
Air conditioner BTUs are recommended based on the square footage of a room. A room that is 20'x28'x15' high has a square footage of 560, as the height is not usually factored in. A room that is 560 square feet should have an AC with at least 18,000 BTUs. Because of your high ceiling, though, consider one with at least 20,000.
The area of all the surfaces in the room is: 2*(27*15 + 15*8 + 8*27) = 2*(405 + 120 + 216) = 2*741 = 1482 sq ft
10-ft x 15-ft = 150 square feet = (16 and 2/3) square yards
It is √(x15), which can be simplified to approx 3.873*√x.
1500 cubic feet, ft3
That's about 23' by 23' or 3 rooms just under 12'x15'. Mentally think of one of the 12'x15' rooms split into the kitchen and bathroom space and some of the other room area should be closet space. If it's a studio, it would be one large room with kitchen and bathroom space.
40'x15' = 600 sq ft = 600/9 sq yards = 66.66... sq yards.
15m x 15m = 225 square meters.
