Question

1. In an average year, 100 cm of rain falls on a catchment area of 900 km2.
a. What is the volume of water received during an average year in cubic meters? ____________________
b. What is the same volume expressed in gallons? ____________________

Answer 1

The volume of water received during an average year is 900,000 cubic meters.

The same volume expressed in gallons is 237,754,800 gallons³.

What is the volume in cubic meters?

Volume =  length x width x height

Volume =  area x height

We have to convert cm to meters and km to meters

100 cm = 1meter

1000m = 1 km

900km = 900,000m²

Volume =  1 x  900,000m² =  900,000m³

What is volume expressed as gallons?

1 meter = 264.172 gallons

900,000 x 264.172 = 237,754,800 gallons³
