Question

1 A rectangular prism has a base that is 6 meters by 3.5 meters, and the prism is

9 meters high. What is the surface area of the prism?
A 213 square meters
C 150 square meters
B 171 square meters
D 106.5 square meters

Answer 1

• A) 213 m²

--------------------------------

Given:

• Dimensions of prism: 6m × 3.5m × 9m

Total surface area:

• S = 2(lw + lh + wh)
• S = 2(6*3.5 + 6*9 + 3.5*9) = 2(106.5) = 213 m²

Correct choice is A.
