A cargo trailer pictured below can be modeled by a rectangular prism and triangular prism. Inside the trailer, the rectangular prism measures 6 feet wide and 10 feet long. The walls that form the triangular prism each measure 4 feet wide inside the trailer. The diagram below is of the floor, showing the inside measurements of the trailer. If the inside height of the trailer is 6.5 feet what is the total volume of the inside of the trailer to the nearest cubic foot?
