A water tank measures 2m*4m*5m.

what mass of water will it contain

mass=densityWater*volume

so what is the density if the volume is 40? this is whhat's confusing me

M=1g/cm^3×(200×400×500)cm=40 000 000g

To calculate the mass of water, we need to know its density. The density of water is typically around 1000 kilograms per cubic meter (kg/m³).

To find the mass, we need to multiply the volume of the water tank by its density. The volume of the tank is given as 2m × 4m × 5m:

Volume = length × width × height
Volume = 2m × 4m × 5m
Volume = 40 cubic meters (m³)

Now, we can use the formula:

Mass = Volume × Density

Mass = 40m³ × 1000kg/m³
Mass = 40,000 kilograms (kg)

Therefore, the water tank will contain 40,000 kilograms (kg) of water.
