Answer 1

Please someone HELP!!!!!!
Thank you :)

Answer 2

The area of a square varies as the square of the variation of the sides.
If the side dimension is doubled, the area will be quadrupled.

\[A=l ^{2}\] now the l dimension is doubled and becomes 2l
\[A=(2l)^{2}=4l ^{2}\]\[4l ^{2}\over l ^{2}\] is 4 or area quadrupled.

Answer 3

Don't know what you need for sure, but that was my "conjecture"

Answer 4

oh, ok. thanx
now using ur conjecture to write a ratio of surface areas and volumes if the dimensions of two similar rectangular prisms are l, w, h, and kl, kw, kh.

Answer 5

yes same thing radar was saying...if the scale factor is k then for surface area the ratio will be k^2 and volume will be k^3

Answer 6

take a rectangular prism for example
Area1 = 2lw +2lh +2wh = 2(lw+lh+wh)
Area2 = 2k^2lw +2k^2lh +2k^2wh = 2k^2 (lw+lh+wh)

Volume1 = l*w*h
Volume2 = lk*wk*hk = k^3 *l*w*h
