A farmer is building a grain silo for storage. He estimates that will need 256 cubic yards of storage. The grain silo will be shaped as a cube. How long should one side of the grain silo be? (Recall that the volume of a cube is calculated by l*3 where l is the length of one side).

Given: Volume = 256 cubic yards. We just need to get the cube root of the volume. Get the factors of 256 that has a whole number as its cube root and get the cube root. Each side of the cube will measure 4 ∛4 yards or 6.35 yards.
