\n" ); document.write( "Justin is remodeling his garden and decides to create a simple swimming pool. He plans to dig and build out a rectangular hole and line it with spray on cement. The dimensions of the walls are as follows: height= 1.5m, length=5m and breadth=3m.
\n" ); document.write( "1.1. what is the surface area of the inside of the pool?
\n" ); document.write( "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.
\n" ); document.write( "1.3. Calculate the percentage of the pool that could be filled by the water in the tank. (Remember 1m^3 =1000litres).

\n" ); document.write( "\n" ); document.write( "the surface area of the inside of the pool is the area of the bottom plus the area of the sides\r
\n" ); document.write( "\n" ); document.write( "the area of the bottom is \"2%2Alength%2Abreadth+=2%2A5m+%2A3m+=30m%5E2\"
\n" ); document.write( " the area of the two parallel sides is \"2%2Alength%2Aheight+=2%2A5m+%2A+1.5m=15m%5E2\"
\n" ); document.write( " the area of the two other parallel sides is \"+2%2Abreadth+%2Aheight=2%2A3m%2A1.5m=9m%5E2\"\r
