The formula of that is 24
3 piano solos....each is 5/12 hr....
u can either add : 5/12 + 5/12 + 5/12 = 15/12 = 1 1/4 hrs
or u could multiply : 3 * 5/12 = 15/12 = 1 1/4 hs
either way....same answer
Part a)
The shape of the pool is rectangular prism, so the volume of the pool will be:
Volume = Length x Width x Depth
Volume = 6 x 3 x 1 = 18 cubic meters
Density of water = 1 gram per cubic centimeter
Density of water = 1,000,000 gram per cubic meter
Density of water = 1000 kilogram per cubic meter
Mass, volume and density are related by the following equation:
Mass = Density x Volume
Using the values, we can write:
Mass of water in pool = 1000 x 18 =18,000 kilogram
Part b)
Mass of water added to pool = 6000 kilograms
Density of water = 1000 kilogram per cubic meter
Volume = Mass/Density
Volume of water in the pool = 6 cubic meter
Since Volume = Length x Width x Depth
6 = 6 x 3 x Depth
⇒ Depth = 1/3 meters
To get a full hour we need to multiply the quantity (1/5) by 5 because this = 1. Now you would have to also multiply the (2/3) by 5.
10/3 miles or 3 and 1/3 miles
