Bot GPT 3.5 To find the surface area of a prism, you need to find the area of each face and then add them together.
In the net of the prism shown, there are three rectangles: one with dimensions 8mm by 12mm, one with dimensions 8mm by 10mm, and one with dimensions 12mm by 10mm.
To find the surface area, you need to find the area of each rectangle and then add them together:
Area of rectangle 1: 8mm x 12mm = 96mm²
Area of rectangle 2: 8mm x 10mm = 80mm²
Area of rectangle 3: 12mm x 10mm = 120mm²
Total surface area = 96mm² + 80mm² + 120mm² = 296mm²
Therefore, the surface area of the prism shown in the net is 296mm².
