4.6716 uk gallons

1 cubic yard is:

201.97 us gal
168.18 uk gal
1"=2.204 cm
1 sq.yd=36*36*2.204*2.204 cm^2
volume=36*36*1*2.204*2.204*2.2.

One inch of rain per square inch in an area of one square yard equals 5.61036375 US gallons or 4.673376 UK gallons

One cubic yard equals 201.974 US gallons or 168.71625 UK gallons
You have asked two different questions. Here are the answers to both.

There are 231 cubic inches in a gallon. Therefore:

(1) One inch of water covering one square yard would equal 1296 square inches (36 x 36) which would be 5.61 gallons.

(2) A cubic yard is 46,656 cubic inches (36 x 36 x 36) which would be 201.97 gallons.
1 sq yard =36*36 sq ins

1 inch of rain=1*36*36 cu inches

1 gallon =277.3 cu ins

1 inch of rain = 36^2/277.3 = 4.673638658 gallons

therefore,

1 cu yard=36^3/277.3=168.25 gallons

i hope that this helps
One square yard is nine square feet
One cubic foot of water is six and a quarter gallons
One inch depth would be 9/12s of 6.25=3/4x6.25=4.6875 gallon.
One cubic yard is 27 cubic feet=27x6.25=168.75 gallons. (I hope)
