**1. An olympic pool is 50m long 25m wide and a minimum average depth of 2m**

a) If the pool is filled as specified, what is the mass of water? Denisty of water to be 1.0g/cm^3

b) How long will it take to fill the pool from a standard garden hose, if the flow rate from hose has average of 8 liters per minute?

**2. Homework Equations (density = mass/volume)(volume = LxWxH)**

**3. a) Volume = 25 x 50 x 2 = 2500m^3**

Convert density to kg/m^3, 1g/cm^3 = 1000kg/m^3

mass = 2500 x 1000 = 2.5e5kg

b) I just did m^3 into liters, so 2500m^3 = 2.5e5liters

2.5e5/8

I know its basic question, with unit conversation etc, but I have no answers to check my working. Thanks
