The volume of the rectangular prism is

$l \times b \times h =112 cm^3$

Let the scale factor be

If we multiply each of the dimensions by k, then we have,

lk, bk, hk

as our new dimensions

Then the new volume is

$lbh \times k^3 = 1.75 cm^3$

But

lbh = 112 cm^3

$\Rightarrow 112 \times k^3 = 1.75 cm^3$

$\Rightarrow k^3 =\frac{1.75}{112}$

$\Rightarrow k^3 =\frac{1}{64}$

$\Rightarrow k=\sqrt(\frac{1}{64})$

$\Rightarrow k=\frac{1}{8}$

Hence the scale factor is

$\frac{1}{8}$
