What do you mean by size?
If you want the dimensions of the room that have that floor area, then assuming a rectangular room, they can be almost any size you want as long as the length x width = 100 sq ft, for example:
10 ft x 10 ft
5 ft x 20 ft
2 ft x 50 ft
1 ft x 100 ft
1/2 ft (= 6 in) x 200 ft
1/4 ft (=3 in) x 400 ft
They all have a floor area of 100 sq ft (though the latter examples above are very odd rooms)
For other shaped rooms, eg octagonal, the dimensions will be different.
When it comes to volume of the room, that would depend upon the height of the room which would depend on the building in which it is (and where in that building) - our house has rooms that are about 11 ft high and others that are about 8 ft high and others that are about 6 ft 6 in high.
900 sq ft is 900 sq ft. The only limit imposed on the dimensions of the room are that the length must be 30 ft [sqrt(900)] ft. The room cound be 30ft x 30ft, or 3ft x 300ft or 0.3ft x 3000 ft etc.
The area of a room does not determine its dimensions. The area does not even tell you if it is square, rectangular, or some other shape - circular, for example.
The size of 30ft.x10ft. room.
100 ft is larger, because 1 yard is equal to 3 feet. So 3 yards is equal to 9 feet. 100 ft is much larger than 3 yards.
100 ft * 125 ft = 0.287 acres (approx).100 ft * 125 ft = 0.287 acres (approx).100 ft * 125 ft = 0.287 acres (approx).100 ft * 125 ft = 0.287 acres (approx).
20 x20 * * * * * And why not 10 ft x 40 ft? And why do you assume it is square or rectangular?
900 sq ft is 900 sq ft. The only limit imposed on the dimensions of the room are that the length must be 30 ft [sqrt(900)] ft. The room cound be 30ft x 30ft, or 3ft x 300ft or 0.3ft x 3000 ft etc.
That room size can be estimated 15 ft x 40 ft

length times width so if you have a room that is 10 ft by 10 ft then your room is 100 square feet 10 x10 =100
Just multiply the length by the width to get square feet. 100x100=10,000sq ft
