Answer: 432
Step-by-step explanation:
I assume we are talking about natural numbers greater than one. Otherwise, one would be the first square, cube, quad, ... number. So 2^2=4, first, 3^2=9, second, 4^2=16, third. The Nth square number would be (N+1)^2, Nth cube number (N+1)^3.
So answer is (3+1)^2×(2+1)^3=4^2×3^3=16×27=42+120+270=432
