Question

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

Answer 1

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

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