AI explanation

The volume of one hemispherical bowl is found using the formula (2/3) * pi * r^3, which gives (2/3) * (22/7) * 3.5 * 3.5 * 3.5 to equal 89.833 cubic cm. Multiplying this by 42 bowls gives a total volume of 3773.5 cubic cm. Since 1000 cubic cm equals 1 liter, dividing by 1000 gives the required quantity of water as 3.773 liters.
