Answer: The volume of water present are 73.584 liters.
Explanation : Given,
Length of box = 1.75 m
Breadth of box = 0.730 m
Height of box = 0.650 m
Height of water = 2.27 inch = 0.0576 m
Conversion used : (1 inch = 0.0254 m)
To calculate the volume of water by using the formula of volume of cuboid, we use the equation:
where,
V = volume of water
l = length of water = 1.75 m
b = breadth of water = 0.730 m
h = height of water = 0.0576 m
Putting values in above equation, we get:
Conversion used :
Hence, the volume of water present are 73.584 liters.

Answer : The volume of produced at standard conditions of temperature and pressure is 0.2422 L
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of
gas = (740-22.4) torr = 717.6 torr
= final pressure of
gas at STP= 760 torr
= initial volume of
gas = 280 mL
= final volume of
gas at STP = ?
= initial temperature of
gas =
= final temperature of
gas =
Now put all the given values in the above equation, we get:
Therefore, the volume of produced at standard conditions of temperature and pressure is 0.2422 L
