Two Geometry questions.

Answer 1

@sidsiddhartha

Answer 2

I need to know if the first one is correct, and I need help solving the second one.

Answer 3

@Nurali

Answer 4

first one is just=(wieght of grass vale)*(7^3)=(0.15)(7*7*7)

Answer 5

Ok, so I was right on the first. Can you help with the second one?

Answer 6

first find the ratio of volumes

Answer 7

nope the ration of volume is=1728/576
now Volume is a function of the cube of the dimensions
so 1728=(12)^3
and
576=8.32^3
so sides are in a ratio of =12:8.32
do u get it

Answer 8

Not really.

Answer 9

I do get that 343=7^3 right?

Answer 10

volume = (side )^3 so \[(side)=(volume)^{1/3}\]
is'nt it?

Answer 11

I don't know. I think that the answer is 196, but I'm not sure.

Answer 12

sides=12/8.32
so surface area=(sides)^2
\[\frac{ 12^{2} }{ 8.32^{2}}=576/X\]
now solve for X

Answer 13

76?

Answer 14

its 276.88

Answer 15

sorryyyy i messed up
576=8.32^3
it should be 343

Answer 16

It's ok. I'm just glad you didn't give up even when I didn't understand.

Answer 17

343=7^3
so arms ratio are=12:7
ans is 196
aww my hand writing :P
