Answer:
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.
