How much water can be stored in 1 cubic meter tank?

A cubic meter tank can hold exactly 1,000 liters of water, as one cubic meter is equivalent to 1,000 liters. This means that the tank can store a volume of water equal to the dimensions of the tank, which is a cube measuring one meter on each side. Therefore, if the tank is completely filled, it will contain 1,000 kilograms of water, assuming the water density is 1 kg/L.
