1 QUESTION. PLEASE HELP. VOLUME GEOMETRY QUESTION.
mina [271]
Knowing the volume of a 3-D shape is extremely when deciding what materials to use and how much of them to use.  When you know the volume of the different designs is helpful when deciding which material costs less to use but still meets requirements. For example, if you were trying to decide what material to fill your product with, and say the volume of your product is 36^3. You narrow things down to two products, one costing $54 to fill the entire thing. The other costing $60. Because you have the volume, it will be easy to decide which is better based off of the price per square inch. If you didn't have the volume. You would have to make an estimate and potentially make a bad business decision.   

Hope this helps! I apologize for my long response

Shawna took a test that had a total of 20 items. She got 4/5 of the items correct. How many items did she get correct?
ehidna [41]

Shawna got 16 items correct

Step-by-step explanation:

To find the percentage of answers or part of total answers we multiply the fraction with the total number of items.

Given

Total items on test = 20

Correct items fraction = 4/5

Then,

Correct\ items=\total\ items * \fraction\ of\ correct\ answers\\= 20 * \frac{4}{5}\\=\frac{80}{5}\\=16

Shawna got 16 items correct
