find the surface area of this prism. geometry hw

Answer:
395.2 cm²
Step-by-step explanation:
2x12.7x6.72=170.688
2x6.72x5.78=77.6832
2x5.78x12.7=146.812
170.688+77.6832+146.812=395.1832
Answer: A=395.2
Step-by-step explanation:
A=2(wl+hl+hw)
A=2[(12.7x5.78)+(6.72x5.78)+(6.72x12.7)]
A=2(73.406+38.8416+85.344)
A=2(197.5916)
A=395.1832
Rounded to nearest tenth..
A=395.2
