Your answer would be: <em>693.</em>
Explanation:
When finding the area in a problem use <em>L×W×H</em>.
That being said, you now have to multiply the <em>L×W×H</em> (7x9x11)
7 × 9 × 11 = <em>693</em>
So the answer would be <em>693</em> because, if you are finding an area you use <em>L×W×H</em> to find your area.
Answer:
478
Step-by-step explanation:
Surface Area=2(ab+ac+bc)
SA=2((7*9)+(7*11)+(9*11))
I think it is C. 14
r+3+4r-28=45
5r-25=45
5r=70
r=14
