A fishtank with inside dimensions of 50 cm X 25 cm X 30 cm is filled with water. What is the volume in cm3 of water required? What is the mass in grams of the water required? What is the mass in kilograms?

volume = length x width x height = ?cc.

mass H2O = volume x density. You don't have density listed; I assume the author of the problem wants you to assume the density of water as 1.00 g/mL.

To calculate the volume of water required to fill the fish tank, we need to multiply the length, width, and height of the tank:

Volume = Length x Width x Height

Given that the inside dimensions of the fish tank are 50 cm x 25 cm x 30 cm, we can substitute these values into the formula:

Volume = 50 cm x 25 cm x 30 cm
Volume = 37,500 cm³

So, the volume of water required to fill the fish tank is 37,500 cm³.

To calculate the mass of the water, we need to know the density of water. The density of water is approximately 1 gram per cubic centimeter (g/cm³).

Mass = Volume x Density

Substituting the volume we obtained earlier and the density of water, we can calculate the mass:

Mass = 37,500 cm³ x 1 g/cm³
Mass = 37,500 grams

Therefore, the mass of the water required to fill the fish tank is 37,500 grams, or 37.5 kilograms (since there are 1,000 grams in a kilogram).
