Use Geometry to Complete an Engineering Drawing
Problem Statement:

An engineer is creating a drawing for a 3D object using a geometric net. The engineer needs to add one more shape on the right side of the drawing to complete the 3D object. If the engineer is trying to create a right triangular prism (above), what shape must he use? If the total surface area of the object is 636 square inches, what must the width of the new shape be (round to the nearest whole number)? Use the robot to draw the shape on the grid, then run the program to answer the questions. (Note: Both drawings on the grid are right triangles)
