One Yard equals three feet. Thus, four yards equals twelve feet. One foot has twelve inches. If you take the four yards (twelve feet), and add them to three feet, you get fifteen feet. Take the fifteen feet, each one containing twelve inches, and multiply them by twelve. Fifteen times twelve equals 180. Therefore, there are 180 inches in four yards, three feet. 4 (yards) x 3 = 12 (feet) 12+3= 15 (feet) 15 x 12 = 180 (inches)

1500 sq ft * 4 inches = 1500/9 sq yards * 1/9 yards = 18.518518... cubic yards.
there are 432 inches in 12 yards. to find your answer you have to figure out how many feet are in 1 yard. so you figure you have 3 feet in one yard. there are 12 inches in 1 foot. so take 12 x 3 x 12. that gives you 432 inches in 12 yards.
about 26.4 is the volume i think.......
252 - 228 and 3/8 = 23 and 5/8 inches
4 inches = 1/3 foot1 cubic yard = 27 cubic feet(1,200 x 1/3) = 400 cubic feet = (400/27) = 14.815cubic yards (rounded)
Sorry the first answer was in square yds. Cubic yards would be 0.308639
20 feet x 20 ft x .3333 ft = 133.33 cubic feet / 27 cubic feet per yard = 4.94 cubic yards
There are 9 CU FT in a yard....and if this is stated in feet, then take your measurement of 12x21 feet or 252 square feet times (7 inches/12 inches or .5833333 feet) to give you 147 Cubic feet , then divide by 9 CUFT/YD or 16.3333 Cu Yards....about two standard mixer loads
