To find the surface area of the prism, we need to find the area of each of its individual faces and then sum them up.
The prism has:
- 2 rectangular faces with dimensions 5cm by 9cm each (Area = 5cm * 9cm = 45 cm^2 x 2 = 90 cm^2)
- 3 rectangular faces with dimensions 4cm by 8cm each (Area = 4cm * 8cm = 32 cm^2 x 3 = 96 cm^2).
Therefore, the total surface area of the prism is 90 cm^2 + 96 cm^2 = 186 cm^2.
Using the net of the prism shown, what is its surface area?
