If a rectangular solid has a volume of 27 and at least one edge the length of 3,which of the following Must be true?
I,m not sure???

a.The solid is a cube

b.Exactly 4 edges of the solid have a length of 3

c.Exactly 6 edges of the solid have a length of 3

d.The product of the lengths of at least one pair of edges of the solid must equal 9.

    it's D. because
    27/3 = 9 -> which must be the product of the remaining two lengths that are not given.

    That you so.... much for the help- it's been a rough day in Geometry
