[3 marks]2.
A triangular prism has a rectangular base of 6 cm by 4 cm, and a height of 7 cm. If the three rectangular faces are added, what is the total area of these faces?
[3 marks]3.
Construct a cube with a side length of 3 cm. Add the areas of 4 faces. What is the total area you get?
[2 marks]4.
A pentagonal prism has a base area of 20 cm² and five rectangular faces each 10 cm long and 3 cm wide. Add the areas of these five rectangular faces.
[3 marks]5.
A cylinder's surface is made up of two circular faces and the curved surface. If the area of the curved surface is 94.2 cm², and both circular faces are added, what is the total area of the three faces?
[3 marks]6.
A rectangular prism has a length of 10 cm, width 4 cm, and height 6 cm. If you add the areas of the four side faces (excluding the top and bottom), what is their total?
