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?

My thoughts lead me to think D is the answer,but 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.

V = L*W*H = 27.

3*W*H = 27,

Divide both sides by 3:

W*H = 9. Satisfies choice "d".

V = 3*3*3 = 27. Satisfies choice "a".

Since the solid is a cube, choices a,c,

and d appears to be true.

Try to get a 2nd opinion.
