(A) 8 = 2*2*2
(B) 12 =2*2*3
(C) 24 = 2*4*3
(D) 27 = 3*3*3
(E) 69 = 3* 13 * 1..not possible

Among the choices only "69" can't be factored into three integers , each factor greater than One to fit the volume of rectangular solid (V = h * w * d)
So, Answer is E

Sorry if this is a silly question, isn't a cube different from a rectangular solid?

Split the answer options using the prime factorization method, but stop once you can split into 3 smaller factors to save time. The answer choice that is unable to give you 3 number of factors (excluding 1 & itself) is the answer.

A) 8 = 4*2 = 2*2*2 (ok)
B) 12 = 2*6 = 2*2*3 (ok)
C) 24 = 2*12 = 2*2*6 (ok)
D) 27 = 3*9 = 3*3*3 (ok)
E) 69 = 3*23

As 23 is a prime number and cannot be further split other than 1 and itself, E is the answer.

All cubes are rectangular solids but not vise-versa.
