Question

Work out surface area please

Answer 1

• 594 cm

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.
