what is the answer to number 15 p.s. show how u got this ANSWER PLEASE

Answer:
The volume of the rectangular prism is [tex]V=442.341\ cm^{3}[/tex]
The surface area of the rectangular prism is [tex]SA=384.62\ cm^{2}[/tex]
Step-by-step explanation:
we know that
The volume of the rectangular prism is equal to
[tex]V=LWH[/tex]
substitute the values
[tex]V=(12.7)(8.1)(4.3)=442.341\ cm^{3}[/tex]
The surface area of the rectangular prism is equal to the area of its six faces
so
[tex]SA=2(8.1)(4.3)+2(12.7)(8.1)+2(12.7)(4.3)=384.62\ cm^{2}[/tex]
