GOLF BALLS CONTAINER DOWN 60 IN 90 NAME: The elevation and end view of a package for two golf balls are shown. The box is based on a pentagonal prism. Draw the given views Draw a complete development of the box. 20 50 20 y 10 x 32 35 32 72° 32 All sides and exterior angles in a polygon are the same. 32 72° x To get window. You cannot take measurements off window slot from elevation because it is sloping away from you. You bring the two green lines across to the end view, because the end view repersents the true shape of the object. There you can find x and y distances and use these measurements to draw the devlpment correctly. y DOWN 60 IN 90
