Question

attached question, answerer(s) get medals!

Answer 1

Seriously dude, they are the exact same type of questions. You do know how to solve them, right?
18ft^2

Answer 2

Because they are similar, all their corresponding parameters will be in the same ratio. Like height/height = area/area

Answer 3

No, I'm taking a 2 week online geometry course and the professor doesn't expect us to actually learn anything. He's the one who reccomended this website to me. Thanks for the help though!

Answer 4

so in this question,
area1/area2=volume1/volume2
20/45 = 8/x
can you find x from here? :)

Answer 5

thats not going to give the right answer =/

Answer 6

I understand that 20 is proportional to 8, i just don't know how to relate it to 45 and x.

Answer 7

oh right. i am sorry i forgot to insert the powers.
it's 20/45 = 4/9
this is the area which means squared lengths

Answer 8

the ratio of lengths is root of 4/9 = 2/3
now volume is length cubes.
so 8/x = (2/3)^3
relate the smaller volume to the smaller area or length or anything.
so now 8/x = 8/27
x = 27
i hope i helped =(

Answer 9

I'm not expecting to actually learn anything, as the course is almost over, but you did help me understand some of the mechanics of the problem. Thanks!
