The question states that a cubical container with dimensions 10 cm x 10 cm x 10 cm can hold exactly 1 litre of water. We are asked to determine how much water a spherical container with a radius of 10.5 cm can hold.

To compare the capacities of the two containers, we can use the formula to calculate the volume of a sphere: V = (4/3)πr^3, where V is the volume and r is the radius.

Plugging in the given radius of 10.5 cm into the formula, we get V = (4/3)π(10.5)^3.

Evaluating this equation, we find that the volume of the spherical container is approximately 1536.99 cubic centimeters.

To convert this volume into liters, we divide by 1000 (since 1 liter is equal to 1000 cubic centimeters).

1536.99 / 1000 = 1.53699 liters.

Now, looking at the options, we can see that option 3 states that the spherical container can hold "more than 4.5 liters but less than 5 liters of water." Since the calculated volume of 1.53699 liters falls within this range, option
