Respuesta :

The surface area of the triangular prism is 533.6 cm².

Surface area of a triangular prism

  • SA = bh + (x + y + z)l

where

b and h are the base and height of the triangular base. Therefore,

  • b = 12 cm
  • h = 10 cm

Therefore,

x = 12 cm

y = 10 cm

z = 15.6 cm

l = 11 cm

Therefore,

SA = 12 × 10 + (12 + 10 + 15.6)11

SA = 120 + (22 + 15.6)11

SA = 120 + (37.6)11

SA = 120 + 413.6

SA = 533.6 cm²
