Answer:

9 times

Step-by-step explanation:

Let the total area be x.

r = x - f = x - 1/10x = 9/10x

How would you find the volume of a tower created from 1,000 cans that were each 12oz in volume?

vlabodo [156]

Answer:

Multiply the number of cans by the volume of each: 12,000 oz.

Step-by-step explanation:

You find the total volume of more than one can by adding the volumes of the cans involved.

For 2 cans, the volume would be ...

12 oz + 12 oz = 24 oz

When you consider adding numbers more than a couple of times, you start looking for ways to simplify the effort. Multiplication was invented for that purpose. Here, multiplying the volume of 1 can by 1000 is the same as adding the volumes of 1000 cans.

For 1000 cans with volume of 12 oz each, the volume of the total is ...

1000 × 12 oz = 12,000 oz.
