he figure above depicts an agar cube with a side length of 13mm. in a experiment, students submerged the cube in red dye for 12 hours. The red dye permeated 1 mm on each side, as indicated by the shading in the figure. Volume of a rectangular solid: V = lwh Calculate the volume of the agar cube that remained unpenetrated by the red dye.

In order to understand the problems of unwanted infertility in a country — the gambia — where the desire for children and the fertility is very high, a population-based survey was undertaken. all infertile women in 24 randomly selected enumeration areas were assessed. the study included a review of the problems faced and coping mechanisms employed by infertility clients and types of health care available for infertile couples in the different types and levels of the formal and traditional health system. half of the infertile couples failed to seek formal health care, and they have to reach a certain level of care in order to be properly managed. alternative care is often sought. child fostering is also a frequent solution to childlessness. in-depth interviews revealed that traditional care like healers and spiritual leaders are frequently consulted long before formal health care. this delay could be a problem in those cases where infertility is caused by infections.
