Question

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

Answer 1

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)`

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)`
