Question

Select all the situations where knowing the volume of an object would be more useful than knowing its surface area.

A. Measuring the amount of gasoline left in the tank of a tractor.

B. Packing a box with watermelons for shipping.

C. Filling an aquarium with buckets of water.

D. Charging a company for ad space on your race car.

E. Determining the amount of paint needed to paint a barn.

F. Determining the monetary value of a piece of gold jewelry.

G. Deciding how much wrapping paper a gift will need.

Answer 1

The answers are A, B, C, and probably F

Explanation:

Volume is how much space an object takes up, while surface area is how much space is on the surface of the object. In option A, we are measuring how much gas can fit in a tank, so volume is used. B and C are also dealing with filling a container. Options D, E, and G are measuring the surface area because they are asking how much of something is needed to cover the surface of a car, barn, and gift. In option F, assuming that the jewelry is pure gold, not just a metal with a gold coating, volume is used.

Hope this helps!
