Question 1196036

 
{{{height = 1.5m}}}
{{{length =5m }}} 
{{{breadth =3m }}}

1.1. what is the surface area of the inside of the pool?

the surface area of the inside of the pool is the area of the bottom plus the area of the sides

the area of the bottom is {{{2*length*breadth =2*5m *3m =30m^2}}}
 the area of the two parallel sides is {{{2*length*height =2*5m * 1.5m=15m^2}}}
 the area of the two other parallel sides is  {{{ 2*breadth *height=2*3m*1.5m=9m^2}}}

the surface area of the inside of the pool is

Surface Area={{{30m^2+15m^2+9m^2=54m^2}}}
 

1.2.The pool will be covered in two layers of cement. Calculate how much it would cost to line the pool if the cement cost R150.00 per square meter.

R{{{150.00*54=8100}}}

1.3. Calculate the percentage of the pool that could be filled by the water in the tank. (Remember 1m^3 =1000litres).

{{{volume=5m *3m* 1.5m=22.5m^3}}}

{{{1m^3 =1000litres}}} 

{{{22.5*1000litres=22500litres}}}  needed  to fill the pool {{{100}}}%  

 to  calculate the {{{percentage}}} of the pool that could be filled by the water in the {{{tank}}} we need to know {{{how }}}{{{many }}}{{{litters}}} of {{{water}}} {{{is}}} {{{in}}} {{{the}}} {{{tank }}}
