  5. On #27 of the Mid Chapter Quiz, I've found a way to get a square cross section, but I'm not sure how to find the exact edge lengths of the square.. Do I just come up with a random number?

    1. You mean #24, right?

      You could intersect the rectangular prism with planes in two different ways... one yields a 3x3 square and the other a 5x5 square. A 10x10 is not possible, since it would extend beyond the space occupied by the prism.

    1. 5. 377cm^2
      6. 298 in^2
      7. 9600 m^2
      8. 75 ft^2
      9. 7 faces
      10. 12 vertices
      11. 10 vertices
      15. 3 in

      17. 188 in^2
      18. 261 m^2
      19. 141 cm^2
      21. Sample answer.
      Alike: Both have a polygon as a base
      Different: A prism has two bases, a pyramid has one. Lateral faces are rectangles for a prism and isos triangles for a pyramid.

      22. π:1
      23. Sample answer: Her mistake was that in a net some edges appear twice, when the net is folded, those duplicate edges come together to from one edge.

  7. I got #8 wrong... And I notice it says "Cone"?

    To find the area of the triangular prism, would you use a triangular face as the base or a rectangular face as the base?

    1. Yup, obviously #8 is a triangular prism.

      The determination of the base has nothing to do with how the object is resting on the "ground"... remember, we could rotate/transform the "space figure" throughout "space" and none of its characeristics (volume, surface area, shape, etc.) would change.

      For #8, the base figure is a triangle.
