Question

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

Answer 1

Explanation:

The volume of the tank is (100cm x 50cm x 30cm) = 150,000 cm³ . If you're working with water, then water has just about 1 gram of mass in each 1 cm³ . So when this tank is full, it would hold about 150,000 grams of mass in the form of water.
