Given the scale factor say 3:5
the small solid refers to the 3, the large to the 5
set up a ratio
3/5 = smallVolume/largeVolume
3*largeVolume = 5*smallVolume
largeVolume = 5/3 * smallVolume
Now just use the scale factors in the problems and the volume/sa provided

ratios are just fractions
to simplify it
given scale factor m:n
large = small*(n/m)
i dont get fractions or scale factors
ok fractions are parts of a whole
just think of scale factors as fractions
i have one pizza with 8 slices
one slice is a part of the whole pizza
the size of one slice is 1/8 of pizza
two slices is 2/8 of pizza
four slices is 4/8 of pizza
if i have four slices that means i have 1/2 the pizza
because 4 is one half of 8
Now if i double my portion,
i multiply 4 slices * 2=8 slices=whole pizza
the scale factor here is 1:2, 1pizza = 2 portions
i dont know if that helped at all, but find someone to help you understand fractions it is VERY important
okay ill just put it this way.. will someone please just put the number into a formula that i can solve
i did above
"given scale factor m:n
large = small*(n/m) "
smallVolume = 100
largeVolume = (100)*(2/1) = 200
