Final answer:
To compare the volume of a football to that of a table tennis ball, you would use the volume of the table tennis ball as a reference, measure the football's volume, and then calculate how many times larger the football is.
Step-by-step explanation:
To estimate how much larger the volume of a football is compared to a table tennis ball, you would need the volume of the table tennis ball as a reference. If Table A provides the volume of a table tennis ball, you would then measure the football's volume, perhaps by submerging it in water and measuring the displacement, and record it in Table B. The volume of a sphere is calculated using the formula V = 4/3 * π * r3, where r is the radius of the sphere. Since a football is not a perfect sphere, adjustments in the calculation method might be needed, considering the football's prolate spheroid shape.
Selecting the appropriate unit for the volume of a football would most likely be cubic centimeters (cm3) or liters (L), while for a table tennis ball it would typically be cubic centimeters (cm3). To compare the volumes, you can divide the volume of the football by the volume of the table tennis ball to find out how many times larger the football is.
