A storm dumps 1.0 cm of rain on a city 6 km wide and 8 km long in a 2-h period. How many metric tons (1 metric ton = 103 kg) of water fell on the city? (1 cm3 of water has a mass of 1 g = 10−3 kg.) How many gallons of water was this?

Respuesta :

Answer:

4660194 metric ton

126802560 gallon

Step-by-step explanation:

1 cm = 0.01 m

6 km = 6000 m

8 km = 8000 m

Volume = 0.01 m x 6000 m x 8000 m =  480000 m³

480000 m³ = 480000000 kg of water (density of water = 1000kg/m³)

103 kg = 1 metric ton

480000000 kg = 480000000 / 103 = 4660194 metric ton

1 m³ = 264.17 gallon

480000 m³ = 480000 x 264.172 = 126802560 gallon
