First, convert everything to the same units: four inches = 1/3 feet. So, the volume is 10 x 10 x 1/3 = 331/3 cubic feet. There are 27 (33) cubic feet in a cubic yard, so you would need 331/3 / 27 =...
1.85 yards (.5 x 10 x 10 ) divided by 27 where .5= the 6 inches converted to feet and 27 is the converstion to cubic yards
10 " = 0.277777 yds.
4'10" is equal to 48+10 or 58 inches.
10 yards equals 30 feet which equals 360 inches.
