Question

3. The fish tank shown at right needs to be cleaned. The cleaning product instructions state that three drops should be put in the tank for every 140 cubic inches of water. How many drops of cleaner should be used?​

Answer 1

Drops = 27

First, we need to find the volume of the given tank using the following equation

$Volume = Length*Width*Height\\Volume =14*9*10\\Volume =1260$

Now that we know the volume, we need to find out how many drops that we need to use. We can find that out using the following equation

$Drops = 3\frac{Volume}{140} \\Drops = 3\frac{1260}{140} \\Drops = 3(9) \\Drops = 27$
