Could somebody explain this question to me? A 1/50 scale model of a pond is present. If the volume of the scale model is 4 cm^3, then the volume of the actual pond is..? the answer is 1/2 m^3. I would like to know HOW. Also.. A drawer has 6red socks and 6 white socks. If you reach in the drawer and randomly take out two socks, what is the chance(probability) that the two socks will match in color? answer is 3/8.
