could someone please break this down and show me how to do it?

A fishtank with inside dimensions of 30.5 cm X 61 cm X 30.5 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

The fishtank above measures 1 ft X 2 ft X 1 ft in English dimensional units. If water weights 62.4 lbs/ft3, what is the weight in lbs of the water filling the tank?
124.8lbs/ft3

1. V = 30.5 * 61 * 30.5 = 56,745cm^3.

2. m = 56,745cm^3 * 1g/cm^3 = 56,745g.

3. m = 56,745g / 1000g/kg = 56.745kg.

4. V = 1 * 2 * 1 = 2ft^3.

2ft^3 * 62.4lb/ft^3 = 124.8 Lbs.

To find the volume of water required in cm³, we can calculate the product of the dimensions of the fish tank. In this case, the length is 30.5 cm, the width is 61 cm, and the height is 30.5 cm. So the volume can be calculated as follows:

Volume = Length × Width × Height
Volume = 30.5 cm × 61 cm × 30.5 cm
Volume ≈ 56,608.25 cm³

Therefore, the volume of water required is approximately 56,608.25 cm³.

To find the mass of the water required in grams, we need to know the density of water. The density of water is approximately 1 g/cm³. Since the volume of the water required is 56,608.25 cm³, the mass can be calculated as follows:

Mass = Volume × Density
Mass = 56,608.25 cm³ × 1 g/cm³
Mass = 56,608.25 g

Therefore, the mass of the water required is 56,608.25 grams.

To convert the mass from grams to kilograms, we divide the mass by 1000 (since there are 1000 grams in a kilogram). Therefore:

Mass in kilograms = Mass in grams / 1000
Mass in kilograms = 56,608.25 g / 1000
Mass in kilograms ≈ 56.60825 kg

Therefore, the mass of the water required is approximately 56.60825 kilograms.

Now, let's calculate the weight of the water filling the tank in pounds. We are given the density of water as 62.4 lbs/ft³.

First, let's calculate the volume of the tank in cubic feet. Since the dimensions are given in feet, we can easily calculate the volume by multiplying the length, width, and height:

Volume = Length × Width × Height
Volume = 1 ft × 2 ft × 1 ft
Volume = 2 ft³

Now, let's find the weight of the water by multiplying the volume by the density:

Weight = Volume × Density
Weight = 2 ft³ × 62.4 lbs/ft³
Weight = 124.8 lbs

Therefore, the weight of the water filling the tank is 124.8 pounds.
