I wish to have 5 cubic yards of dry sand delivered to my yard.
How big (diameter and height of cone) will the pile of sand be?
:
Assuming the height of the pile is half the diameter (equal to the radius)
convert 5 cubic yds to cu/ft: 5*27 = 135 cu/ft
:

= 135
multiply both sides by 3
= 405
=
= 129
Find the cube root of both sides
r ~ 5 ft
:
A pile with a 10 ft diameter and a height of 5 ft, for 5 cu/yds
