1.
Calculate the surface area of a square-based pyramid with a base side of 6 cm and a slant height of 8 cm using the net method.
[3 marks]2.
Construct the net of a pyramid with a rectangular base measuring 10 cm by 14 cm and an apothem of 9 cm. Calculate its total surface area.
[4 marks]3.
A pyramid has a triangular face with a base of 5 cm and a slant height of 7 cm. Find the area of that face.
[2 marks]4.
Using the net of a pyramid with a square base (side 4 cm) and four triangular faces, determine the total surface area.
[4 marks]5.
A student draws the net of a pyramid but forgets to include one triangular face. How does this mistake affect the calculated surface area?
[3 marks]6.
Given a pyramid with a base area of 36 cm² and a lateral face area of 18 cm², find the total surface area.
[3 marks]7.
A pyramid's net is shown with a square base and four triangles. If each triangular face has an area of 8 cm² and the base side is 4 cm, calculate the total surface area.
[4 marks]8.
A pyramid has a base with side length 9 cm and a slant height of 12 cm. Construct its net and find the surface area.
[4 marks]9.
Identify and correct the mistake in this net: The total area of the faces is calculated as 120 cm², but the actual surface area is 150 cm². What went wrong?
[3 marks]10.
A challenge: A pyramid with a base of 8 cm and a slant height of 10 cm has a net with all faces correctly drawn. Calculate the total surface area, explaining each step.
[5 marks]11.
Estimate the surface area of a pyramid if the net is poorly constructed, with some faces overlapping or missing. Why is accurate net construction important?
