Question

Convert the 2. 2 centimeters of runoff results from a storm on a drainage area of 250 kn depth of runoff (2 cm) to the volume (cubic meters). (2 marks)

Answer 1

Answer:

$volume  =  5\times 10^6 m^3$

Explanation:

Given data:

Height is given as 2.2 centimeters

Area is given as 250 km^2

we know that volume is given as

$volume  = area \times height$

from the above we have

height $2.2 cm = 2.2\times 10^{-2} m$

$area = 250 km^2 = 250\times 10^6 m^2$

so volume is

$volume  = 250 \times 10^6 \times 2.2\times 10^{-2}$

$volume  =  5\times 10^6 m^3$
