Think of this cement traffic barrier as a rectangular prism with a trapezoidal prism on top. A solid is a triangular solid on a rectangular solid. The rectangular solid has a length of 380.0 centimetres, width 66.0 centimetres and height 25.5 centimetres. The triangular solid has the upper part removed at a height of 50 centimetres from the rectangular solid to form an upper face with a width 23.0 centimetre. What is the area of the base of each prism? What is the volume of each prism? What is the total volume of the cement needed to make the traffic barrier?
