A student recorded how long complete diffusion of a dye into agar blocks of different sizes took while the blocks were suspended in the dye. The results are shown. What is the predicted time for complete diffusion of the dye into the agar block measuring $5\,\text{mm} \times 10\,\text{mm} \times 15\,\text{mm}$?
