Multipy all sides by 4

Answer 2

i just dont get this crap

Answer 3

Because its cubic inches it will increase the volume by 64x i think...

Answer 4

So think about it like this

Answer 5

if its a square and its s scale factor of 2 its twice as muich as one so the sides arfe all twice as big

Answer 6

if its square inches its not only twice as big area but 4x because 2^2 =4

Answer 7

If its cubic inches its not 2 but 8 because 2^3=8. See now?

Answer 8

1 is the normal figure. if the scale is 2 then its twice as big as 1.

Answer 9

Answer 10

um not really still ;( so how they got 4 was 2^2? so how do i get the answer though lol sorrry

Answer 11

The normal scale increases by 2 but because your working in in^2 or inches SQUARED you also square the factor you increase by.

Answer 12

so 50 ^2?

Answer 13

Answer 15

Your base number is 1 ok?
your scale is 4
4 is 1*4
so all the sides of your figure are x4 as big
but because your working in cubic units you want to make a shortcut and cube the 4
then multiply that number *50
