**Reiny**, Wednesday, April 9, 2014 at 8:35pmDimensions of the rectangle including the sidewalk is

290 by 730 , (added 5 feet on each side)

surface area of sidwwalk

= 290x730 - 280x720

=10100 ft^2

volume of sidwwalk

= 10100(8/12) ft^3

= 20200/3 ft^3

but we are ordering 5% extra

volume ordered

= 20200/3 (1.05)

= 7070 cubic ft

= 7070/27 cubic yards

= 261.85 cubic yards

BUT we will probably have to order 262 yds^3

for a cost of

262(74.50)

= $19,519.00
