1
Find how many complete days fit into 210 hours.

210 ÷ 86,400 = 8.75
This means 210 hours contains8 full days, plus a little extra time.

Find how many seconds are left.
We know that 8 days contain:
8 × 86,400= 691,200 seconds
We started with 756,000 seconds. Subtract the seconds we've already used:
756,000 − 691,200= 64,800 seconds
That leaves 64,800 seconds after counting the 8 full days.
Final answer
210 hours = 8 days and 64,800 seconds
8 full days + 64,800 seconds left over.
