Question from Erika: A lake has 113 feet deep and an area of 115 acres, what is the volume of the lake in cubic kilometer? |
Hi Erika,
This is a place where I think you should use the information that is available to us on the web. I'm a Mac user so I asked Siri.
Me: Hey Seri, what's 115 acres in square kilometers?
Siri: 115 acres is 0.47 square kilometers.
Me: Hey Siri, what's 113 feet in kilometers
Siri: 115 feet is 0.035 kilometers.
Hence I know that the volume of the lake is $0.47 \times 0.035$ cubic kilometers.
