What is the mass of an aluminum cylinder that has a volume of 1.50m^3

To approximate the mass of aluminum cylinder, we use the data on density and the volume of the substance. Density is the mass of a substance over the volume it occupies. Density of aluminum is equal to 2.7 kg/L density and a volume of 1.5 m3 or 1500 L. We multiply the two to get 4.05 kilograms of aluminum cylinder.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
