Answer: 3
Step-by-step explanation:
Let say x the width of the tank,
x+4 its length,
x+2 its height

<u>width=3</u>
length=3+4=7
height=3+2=5
2/3 x 5 = 3
the ratio from 4 to 20 is 5, then you multiply it by the original amount
so it's 3
If 1% is equal to 0.01
and 1/2% is equal to 0.005
then 1 1/2% is equal to 0.015
