Step-by-step explanation:
You only need to isolate the term a to solve this problem.
Add by 3 from both sides.
Solve.
0+3=3
a/7<3
Multiply by 7 from both sides.
Solve.
3*7=21
<u>a<21</u>
As a result, the solution is a<21, which is our answer.
So, when finding the volume, we would just add up every side, and from the question above, it look like that the numbers that we would be adding are the following above.
The volume would be 11.2
The volume would be 11.2
