Find, in simplest radical form, the shortest possible distance in centimeters that could be traced from A to be on this surface of this 12 cm x 16 cm x 36 cm block.

 

This is not the picture given int he question, but it shows where the A and B points are on my questions. Just replace the dimensions in the image, whith the ones given above.

 

Thanks!

The shortest distance on the surface will be along the shortest dimension and then the diagonal of the rectangle

replacing 10 12 20 with   12  16  36 respectively   travel from A along 12cm edge then diagonal of  16 x 36 =4 sqrt97

 

4 sqrt 97  +  12    cm
