The diagram above shows the plan of a drive way to a house. the driveway is made from concrete. the perimeter of the driveway is 64 m. the concrete is 15 m thick. now calculate the volume of concrete used for the driveway. give your answer in cubic meters..a challenging question.. someone me..

First you want to find the area of the driveway. The easiest way to do this is to separate the rectangles. The area of the small rectangle will be 6 because 2x3=6, the area of the large rectangle will be 216 because 18x12=216. Then you will add the two areas back together, 216+6=222. Using the formula volume=baseXheight you will do 222x15 to get 3,330 cubic meters (because height and depth work the same)

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
