Question

The global surface water area is 361, 132,000 square meters. Calculate the volume of water needed to cause a 3mm in sea level.

Answer 1

Given : The global surface water area is 361, 132,000 square meters.

To Find :  the volume of water needed to cause a 3 mm rise in sea level.

Solution:

Volume = surface area * height

surface area  = 361, 132,000 m²

height = 3 mm  = 3 /1000  m

( 1 m  = 1000 mm)

volume of water needed =  361, 132,000  * 3 /1000

= 10,83,396 m³

1 m³ = 1000 litre

=  10,83,396,000  litre

10,83,396,000 litre water needed to cause a 3 mm rise in sea level.

• Calculate the volume of water needed to cause a 3mm in sea level.

$\large \underline{ \underline{ \textbf {\textsf{Solution : - - - }}}}$

we will convert height into meter so, as we know (1m =1000mm) Therefore = height be 3/1000

$\textbf{we know \underline{ \red{\boxed{ \textbf{ \textsf{volume = surface area × height }}}}}}$

Substituting values we get,

$\longmapsto { \sf{volume _{(water)}} = surface \: area \times \: height } \\ \\ \\ \\ \longmapsto { \sf{volume _{(water)}} =36113200 \times \frac{3}{1000} } \\ \\ \\ \\ \longmapsto { \sf{volume _{(water)}} =361132 \cancel{000} \times \frac{3}{ \cancel{1000}} } \\ \\ \\ \\ \longmapsto { \sf{volume _{(water)}} =361132{ \times 3}} \\ \\ \\ \\ \longmapsto { \underline {\boxed {\red{{\sf{volume _{(water)}} =1083 396 {m}^{3} }}}}} \\ \\ \\ \\ \\ \underline {\maltese \: \pmb{ \textbf{ \: we \: will \: convert \: meter \: into \: litre\: }}} \\ \\ \bigg \{1 \: meter \: = 1000litre \bf \bigg \} \\ \\ \bf therefour = 1083396 \times 1000 = 1083396000$
