even if they dont give you the area you can still find it by multiply the lenght with width which gives you 720. To find out the amount of sand you mutliply 720  by 2 which gives you one of the options

anonymous · Answer

therefore 1440 cubic feet of sand is needed:)

anonymous · Answer

Sorry but the 2 is 2 inches, or 1/6 of a foot.  Thus multiply720 by 1/6 to get 120.

$$36*20*\frac{1}{6}=120 \text{ ft}^3 $$
