u would first find out how many inches are in 30 feet by mutipling 30 times 12 and get 360 inches.then u would find how many yards are in 360 by dividing 360 divided by 36 inches and get 10.
30 ft
90 ft = 30 yards
1 yard = 3 feet 30 divded by 3 = 10 yards
30 feet is 10 yards.
90 feet is 30 yards.
5X30=150sq. ft. 150 sq. ft. / 9 sq. ft./sq. yard = 16.7 sq. yards
270 ft squared is for example 30 ft x 9 ft. this can be converted as 10 yards x 3 yards which is 30 square yards.
If the units are 30 ft x 30 ft x 4 inches, then you have 30 x 30 x 0.33 ft = 300 cubic feet300 cubic ft/27 cu yds/cu ft = 11.1 cubic yards
10...3 ft. per yd.
21 ft. = how many yards
30 ft * (1 yard/3 ft) = 10 yards.
10 yards.
