62.33(19)=1184.27 sq feet
:
Volume is 1184.27(2/3)=789.91 cubic feet
:
remember 1cu yd =27 cubic feet, so we have to divide by 27 to get cu yd's
:
789.91%2F27=29.26cu yd's
:
rounded:highlight%2829%29cu yd's

A cubic yard is 1 yd x 1 yd x 1 yd = 1 yd3
1 yd = 3 ft, so
3 ft x 3 ft x 3 ft = 1 yd3
and
3 ft x 3 ft x 3 ft = 27 ft3
27 ft3 = 1 yd3
----
The volume of cement that the driveway will take is
62 1/3 x 19 x 2/3
I'll call this volume v
v+=+%2862+%2B+1%2F3%29+%2A+19+%2A+%282%2F3%29
v+=+%2862+%2B+1%2F3%29%2A%2838%2F3%29
v+=+%28187%2F3%29%2A%2838%2F3%29
v+=+7106%2F9
v+=+789.55 ft3
v%5By%5D+=+789.55%2F27 yds3
v%5By%5D+=+29 yds3
