Answer:

  • 594 cm

Step-by-step explanation:

We know that:

  • Surface area of prism = Area of rectangle + Area of triangle

Solution:

  • Surface area of prism = (30 x 17) + (1/2 x 21 x 8)
  • => Surface area of prism = (510) + (21 x 4)
  • => Surface area of prism = (510) + (84)
  • => Surface area of prism = 594 cm

Hence, the surface area of the prism is 594 cm.
