Worksheet directions

Grade 6 • Independent Practice • Work on your own. Show your calculations or reasoning where needed.

Sample questions

  1. Four triangular panels with base 4 cm and height 8 cm form a pyramid-shaped roof without a base panel. Find the panel area. How much would adding a square base increase it?
  2. A square pyramid has base side 6 cm and each triangular face has perpendicular height 6 cm. Draw a net and calculate surface area.
  3. A student computes only the four triangular faces and calls that the total surface area. Explain which face is missing and find the full area in square centimeters.
  4. The net has a square base and four congruent triangular faces. Measurements are in centimeters; the dashed segment is a triangle’s height. Find the surface area.
  5. A square pyramid has base side 5 cm and each triangular face has perpendicular height 6 cm. Draw a net and calculate surface area.
