Answer:

  −72.8

Step-by-step explanation:

Your calculator can help with this.

The odd number of minus signs among the factors means the product will be negative.

The product will be less than 7×4×3 = 84, so -728 and the two positive numbers are eliminated as possibilities.

The only reasonable choice is -72.8.
