Answer:
B. 540 cubic inches
Explanation:
Let's start with the formula.
Or:
We are given the Length, Width, and Height.
So we just multiply it out:
The volume is 600 cubic inches
But we aren't done yet:
We now have to find 90% of 60, and we can do that in two ways
Set up a percent proportion:
Or we could use benchmark fractions.
To find 90% of 600, we do 600 - (10% of 600)
This is just 600 - 60
540
