A pet supply company makes a small bag that holds 2 pounds of dog food. They want to make a bag for large dogs that holds 40 pounds of dog food.
By approximately what factor will the surface area of the bag increase? Round your answer to the nearest tenth, and place this answer, and how you got there, in the
discussion.

Answer 1

Answer:.

Explanation:

The increase in surface area of the bag is by a factor of 20.

Scaling

Scaling is the increase or decrease in the size of an object or figure by a factor k, so as to create an image.

Given that the bag size is increased so as to carry more food, hence:

Scale factor = 40 pounds / 2 pounds = 20

The increase in surface area of the bag is by a factor of 20.
