Practice Questions
Answer all questions carefully. Show your working in the grid spaces provided where applicable.
1.
Calculate the total surface area of a rectangular prism with length 8 cm, width 5 cm, and height 10 cm by first drawing its net and then computing the area.
[4 marks]2.
Construct the net of a triangular prism with a triangular base of side length 6 cm and a height of 4 cm, and rectangular sides of 6 cm by 8 cm. Show all faces clearly.
[4 marks]3.
A prism has a square base with side length 12 cm. Its height is 15 cm. Draw its net and determine its surface area.
[4 marks]4.
Identify and correct the mistake in the following net of a cube: one face is missing, and the remaining faces are arranged in a line.
[3 marks]5.
A compound prism consists of a rectangular prism stacked on top of a triangular prism. If the rectangular prism has dimensions 8 cm by 4 cm by 10 cm, and the triangular prism has a base of 4 cm, height 3 cm, and length 8 cm, draw the combined net.
[5 marks]6.
Calculate the total surface area of a hexagonal prism with a side length of 5 cm, where the height of the prism is 10 cm.
[4 marks]7.
Given the net of a pentagonal prism, identify the faces that are congruent and explain how the net corresponds to the 3D shape.
[3 marks]8.
A toy block is in the shape of a rectangular prism with dimensions 9 cm by 5 cm by 3 cm. Its net is to be used for manufacturing. Show the net and compute the surface area.
[4 marks]9.
Construct a net for an octagonal prism with side length 4 cm and height 7 cm. Indicate all faces clearly.
[5 marks]10.
Identify a common mistake students might make when calculating the surface area of a prism from its net, and explain how to avoid it.
[3 marks]11.
A large cylindrical tank is designed with a rectangular net for the sides. If the height is 20 meters and the rectangular face measuring 15 meters by 20 meters, draw the net and calculate the total surface area.
