10 is the legnth of the triangle face
8 is the height
6 is the long side of the base
Solve for the surface area of the triangular prism.
(1 point)
• 180 square centimeters
• 320 square centimeters
• 260 square centimeters
• 280 square centimeters
Surface area of a triangular prism = 2*(base area) + (perimeter of base)*(height)
Base area = (1/2)*length*height = (1/2)*10*8 = 40 square cm
Perimeter of base = sum of all sides = 10 + 8 + 6 = 24 cm
Surface area = 2*40 + 24*8 = 80 + 192 = 272 square cm
Therefore, the correct answer is closest to 280 square centimeters. The closest option is 280 square centimeters.
