Algebra.Com's Answer #316711 by math-vortex(648)![]() ![]() You can put this solution on YOUR website! you are monitorina a V-shaped channel that carries water runoff from a section highway. the channel is 8feet deep, 10 feet across, and 1/2 mile long. when the the water is 61/2 deep, about how many cubic feet of water will ther be in the channel? \n" ); document.write( "===================== \n" ); document.write( "The shape of the channel is a triangular prism. (the underwater v-shape sides, and a line drawn from side to side on the surface form an inverted triangle. The distance of the channel adds the other dimension. \n" ); document.write( ". \n" ); document.write( "We need to use the formula for the volume of this shape to find the amount of water contained in it. The formula for the volume of a triangular prism is \n" ); document.write( "V = [the area of the triangle] x [the length of the channel]. \n" ); document.write( ". \n" ); document.write( "The formula for the area of a triangle is \n" ); document.write( "A = [1/2] x [base] x [height]. \n" ); document.write( "In your problem, the base of the triangle is the distance across the channel (10 ft.), and height of the triangle is the depth of the channel (8 ft.). \n" ); document.write( ". \n" ); document.write( "The channel is 1/2 mile long. We need to convert this to feet. There are 5,280 feet in one mile, so there are 2,640 feet in a half-mile. \n" ); document.write( ". \n" ); document.write( "Let's use our formula to put this all together: \n" ); document.write( "V = (1/2)*(10)*(6.5)*(2640) \n" ); document.write( "V = 85,800 \n" ); document.write( ". \n" ); document.write( "There are 85,800 cubic feet in the channel. \n" ); document.write( ". \n" ); document.write( "Hope this helps! \n" ); document.write( ". \n" ); document.write( "Ms.Figgy \n" ); document.write( "math.in.the.vortex \n" ); document.write( " \n" ); document.write( " |
