Find the surface area of the prism
A. 90 cm^2
B. 96 cm^2
C. 150 cm^2
D. 156 cm^2
2 answers:
Step-by-step explanation:
SA = 12(3 + 4 + 5) + 2(½ × 3 × 4)
SA = 12(12) + 2(2 × 3)
SA = 144 + 2(6)
SA = 144 + 12
SA = 156 cm²
Therefore
Surface area of prism is 156 cm². Option D
Answer:
Step-by-step explanation:
<u>The full surface area is:</u>
- S = Ph + 2B = (3 + 4 + 5)*12 + 2(1/2*3*4) = 144 + 12 = 156 cm²
Correct choice is D
