This Instructional Activity is a part of the Lesson 26, Unit 6, Grade 7. A box with a length of 2, a width of 1.5, and a height of 1.25 contains fragile electronic equipment that is packed inside a larger box with three inches of styrofoam cushioning material on each side (above, below, left side, right side, front, and back). Give the dimensions of the larger box. Design styrofoam right rectangular prisms that could be placed around the box to provide the cushioning (i.e., give the dimensions and how many of each size are needed).
