To find the result of this expression, we need to convert all the measurements to the same unit (centimeters) and then perform the multiplication and subtraction.

8m 7dm = 8m + 70cm = 800cm
6dm = 60cm
3m - 45cm = 300cm - 45cm = 255cm
1h 18min = 60min + 18min = 78min = 1h 18min = 4680sec

Now we multiply the measurements:
800cm 60cm 4 255cm 4680sec = 582,696,000 cm

Therefore, the result of the expression is 582,696,000 cm.
