Answer:
<em>15 times and more. After she pours the 15th container, in the middle of the next one, the work will be done.</em>
Step-by-step explanation:
<u>Length, Area, and Volume Scale Factors</u>
If two similar shapes have a length scale factor of a:b, then the scale factor of their areas (or surface lateral areas) is
and the scale factor of their volumes is
.
We are given the scale factor of the surface areas of two similar containers A and B as 4:25.
The length scale factor is

The volume scale factor is:
= 125:8 = 15.625
Warda needs to fill with oil and pour into container B 15.625 times to get container B full of oil.
Thus, after she pours the 15th container, in the middle of the next one, the work will be done
