What mass of water in grams will fill a tank 100 cm long, 50 cm wide, and 30 cm high

150000 g

Explanation:

Firstly, we need to calculate the volume of the tank :

(1)

Now, is the volume that has to be filled with water, this means the volume water occupies in the tank must be equal to the volume of the tank:

(2)  

On the other hand, the density of water is and establishes the relation between its mass and its volume :

(3)  

Clearing :

(4)  

(5)  

Finally:
