To express a time period of exactly 6 days in terms of seconds, we need to convert days into hours, then hours into minutes, and finally minutes into seconds.

Step 1: Convert days to hours

$1 \, \text{day} = 24 \, \text{hours}$ $6 \, \text{days} = 6 \times 24 \, \text{hours} = 144 \, \text{hours}$

Step 2: Convert hours to minutes

$1 \, \text{hour} = 60 \, \text{minutes}$ $144 \, \text{hours} = 144 \times 60 \, \text{minutes} = 8640 \, \text{minutes}$

Step 3: Convert minutes to seconds

$1 \, \text{minute} = 60 \, \text{seconds}$ $8640 \, \text{minutes} = 8640 \times 60 \, \text{seconds} = 518400 \, \text{seconds}$

Final Answer:

$6 \, \text{days} = 518400 \, \text{seconds}$
