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.
375 square feet.
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.
240 square feet
300 square feet. This is an easy calculation - just multiply the length by the width. The answer is the number of square feet.
It is 4 times 15 = 60 square feet
15'x15' is 225 square feet; so I would figure on 225 tiles. I would get a few extras in case some crack.
12' * 15' = 180 sq ft = 180*0.0929 sq m = 16.72 sq m (to 2 dp)
40'x15' = 600 sq ft = 600/9 sq yards = 66.66... sq yards.
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.
