Answer:

The volume of the rectangular prism is V=442.341\ cm^{3}

The surface area of the rectangular prism is SA=384.62\ cm^{2}

Step-by-step explanation:

we know that

The volume of the rectangular prism is equal to

V=LWH

substitute the values

V=(12.7)(8.1)(4.3)=442.341\ cm^{3}

The surface area of the rectangular prism is equal to the area of its six faces

so

SA=2(8.1)(4.3)+2(12.7)(8.1)+2(12.7)(4.3)=384.62\ cm^{2}
