A water reservoir is shaped like a rectangular solid with a base that is 70 yards by 20 yards, and a vertical height of 30 yards. At the start of a three month period of no rain, the reservoir was completely full. At the end of this period, the height of the water was down to 4 yards. How much water was used in the three month period?
\n" ); document.write( "------------
\n" ); document.write( "\"... down to 4 yds ...\" means a loss from 30 yds in height, = 26 yards.
\n" ); document.write( "------------
\n" ); document.write( "Used = 70*20*26 cubic yards
\n" ); document.write( "---------------
\n" ); document.write( "Cubic yards of water?
\n" ); document.write( "Acre-feet of water?
\n" ); document.write( "Units other than metric are silly.
