The expression is a bit invalid. You can't add variables by variables.
The amount of packing material is 1506 cubic inches
<h3>How to determine the amount of
packing material?</h3>
The given parameters are:
<u>Can</u>
Radius, r = 7 inches
Height, h = 18 inches
<u>Box</u>
Base dimension, l = 15 inches
Height, h = 19 inches
The volume of the can is:
![V = \pi r^2h](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20r%5E2h)
So, we have:
![V_1 = 3.14 * 7^2 * 18](https://tex.z-dn.net/?f=V_1%20%3D%203.14%20%2A%207%5E2%20%2A%2018)
![V_1 = 2769](https://tex.z-dn.net/?f=V_1%20%3D%202769)
The volume of the box is
![V =l^2h](https://tex.z-dn.net/?f=V%20%3Dl%5E2h)
So, we have:
![V_2 =15^2 * 19](https://tex.z-dn.net/?f=V_2%20%3D15%5E2%20%2A%2019)
![V_2 =4275](https://tex.z-dn.net/?f=V_2%20%3D4275)
The amount of packing material is;
Amount = V2 - V1
This gives
Amount = 4275 - 2769
Evaluate
Amount = 1506
Hence, the amount of packing material is 1506 cubic inches

Answer:
1: something because you didn't give another number. For example, 1:2 is 1 golf ball to 2 golf tees. A ratio is one thing comparing to another. Hope this helps! I learned this in 6th grade. Brainly if so!
