Answer:
B. 540 cubic inches
Step-by-step explanation:
Let's start with the formula.
[tex]Volume=Length*Width*Height[/tex]
Or:
[tex]V=L*W*H[/tex]
We are given the Length, Width, and Height.
So we just multiply it out:
[tex]12.5*6*8=600[/tex]
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:
[tex]\frac{x}{90}=\frac{600}{100}[/tex]
[tex]x=\frac{90*600}{100}[/tex]
[tex]x=540[/tex]
Or we could use benchmark fractions.
To find 90% of 600, we do 600 - (10% of 600)
This is just 600 - 60
540
