As the divisional section consists of _three_ figures, we use the
“hundreds” scale. Setting the cursor to 0·162 on the L.H. A scale, and
using the R.H. index of C, we move the slide to the left until under the
cursor 0·545 is found on the L.H. B scale, while the R.H. index of C
points to 0·545 on D, which is therefore the cube root of 0·162.
