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:
So, we have:
The volume of the box is
So, we have:
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:
As per the statement: the value of the expression 7 x n/4 greater than 7.
To describe the relationship between n and 4.
"greater than" symbol is represented by '>'
The value of expression grater than 7 is;
Divide by 7 both sides we get;
Multiply both sides of an equation by 4 we get;
Therefore, the relationship between n and 4 is,
