Question

7mm 8mm 10mm 6mm
Using the net of the prism, what is its surface area?

Answer 1

To find the surface area of the prism, we need to find the area of each face and then add them up.

The net of the prism is made up of 5 faces:
- 2 faces with dimensions 7mm x 8mm = 56mm^2 each
- 2 faces with dimensions 10mm x 8mm = 80mm^2 each
- 1 face with dimensions 7mm x 10mm = 70mm^2

Total surface area = 2(56mm^2) + 2(80mm^2) + 70mm^2
Total surface area = 112mm^2 + 160mm^2 + 70mm^2
Total surface area = 342mm^2

Therefore, the surface area of the prism is 342mm^2.
