A lake is 928 acres and has a depth of 17 feet, how may cubic feet of water is\r\n" );
document.write( "in the lake?\r\n" );
document.write( "\r\n" );
document.write( "Any shape that has the same shape and area of cross-section all the way through\r\n" );
document.write( "is a prism. The equation for calculating the volume of a prism is the cross-\r\n" );
document.write( "sectional area of the prism multiplied by its length.\r\n" );
document.write( "\r\n" );
document.write( "If we assume the depth everywhere is 17 feet, then the lake is a prism.\r\n" );
document.write( "\r\n" );
document.write( "The area of the lake's cross-section, i.e., its surface is 928 acres\r\n" );
document.write( "\r\n" );
document.write( "Since 1 Acre = 43560 ft², 928 Acres = 928×43560 ft² = 40423680 ft²\r\n" );
document.write( "\r\n" );
document.write( "Volume = (Area of cross-section)×(height, which in this case is depth)\r\n" );
document.write( "\r\n" );
document.write( "Volume = 40423680 ft² × 17 ft = 687202560 ft³\r\n" );
document.write( "\r\n" );
