Explanation:

I) To find the volume of the fish tank in cubic centimeters, we can use the formula for the volume of a rectangular prism:

volume = length * width * height

Plugging in the given values, we get:

volume = 70 cm * 40 cm * 30 cm = 84000 cm^3

So the fish tank will hold 84000 cubic centimeters of water.

II) To find the volume of the fish tank in milliliters, we can first convert the volume in cubic centimeters to liters, then convert the volume in liters to milliliters. One liter is equal to 1000 milliliters, so to convert from cubic centimeters to milliliters, we need to divide the volume in cubic centimeters by 1000.

The volume of the fish tank in liters is 84000 cm^3 / 1000 cm^3/liter = 84 liters.

The volume of the fish tank in milliliters is 84 liters * 1000 ml/liter = 84000 ml.

So the fish tank will hold 84000 milliliters of water.

III) To find the volume of the fish tank in liters, we can convert the volume in cubic centimeters to liters using the conversion factor 1 liter = 1000 cm^3.

The volume of the fish tank in liters is 84000 cm^3 / 1000 cm^3/liter = 84 liters.

So the fish tank will hold 84 liters of water.
