Answer: 72

Explanation:


If you check all the triangles you will notice that the number in the center is actually the result of the 3 numbers outside;

For the first triangle;

(1 x 2 x 3) + (1 + 2 + 3) = 6 + 6 = 12

Similarly, for the second triangle;

(2 x 3 x 4) + (2 + 3 + 4) = 24 + 9 = 33

Therefore, we can find the missing number in the third triangle as;

(3 x 4 x 5) + (3 + 4 + 5) = 60 + 12 = 72

Missing Number =72.
