Answer: 96 square units
Step-by-step explanation: 5 surfaces added together: top & bottom bases, 3 more vertical faces
The areas of the triangular bases [tex]\frac{bh}{2} = \frac{6*2}{2} =6[/tex] Two of them so 12 u²
Front face: 6×7 = 42 u²
Back faces: 3×7 = 21 u² .Two of those, so 42u²
Add those together: 12 + 42 + 42 = 96
Total surface area of the prism is 96 square units
