1 answer

Here are the responses to your questions based on the information provided:

  1. Identify the face, edge, and vertex of the triangular prism.

    • Face: 1
    • Edge: 2
    • Vertex: 3

  2. What is the two-dimensional shape created by the sliced object?

    • Since you mentioned various shapes as options, it would depend on the context of the image. However, if the object is a triangular prism, the typical shape created by slicing it horizontally or vertically would be triangle for a horizontal slice or rectangle for a vertical slice.

  3. What is the surface area of the triangular prism?

    • Assuming you have an image or calculation for this question, a prompt would be necessary, but providing a direct number isn’t possible without specific dimensions. You would calculate it based on the formula given.

  4. Fill in the blanks to complete the formula for the surface area of a triangular prism.

    • The surface area of a triangular prism is \( S.A. = \text{Base Area} + (S1 + S2 + S3) \)
    • Typically, \( S1, S2, \) and \( S3 \) would represent the areas of the three rectangular lateral faces.

  5. How much wrapping paper will Jerry need to wrap the present?

    • To find the surface area of the box (rectangular prism):

      • Surface Area= 2(lw + lh + wh)
      • For dimensions: width = 10 cm, height = 4 cm, length = 17 cm
      • Surface Area = 2(104 + 1017 + 4*17)

      Therefore, calculating:

      • 2(40 + 170 + 68) = 2(278) = 556 cm²
      • Surface area = 556 cm²

  6. How much wrapping paper is needed to wrap the toy in a triangular prism container?

    • Without specific dimensions or the image, you can calculate it similarly to the previous one using the surface area formula for a triangular prism.

  7. What is the shape of the base of a rectangular pyramid?

    • Rectangle

  8. What two-dimensional shape is created by slicing a right rectangular pyramid perpendicular to the base?

    • Triangle (if sliced from a vertex to the midpoint of the opposite edge) or Rectangle (if sliced parallel to the base).
