• Radar emits radio waves that bounce off objects and return to the radar system.

• The time it takes for the waves to return is used to calculate the distance of the object.

• By using multiple radar systems, the location of the object can be determined in three-dimensional space.

• Radar can be used in aviation, maritime navigation, and military applications.

• Radar can als...read more

Quantity of a specific item or material is calculated by multiplying the dimensions and density of the material.

• Calculate volume by multiplying length, width, and height

• Determine density of the material

• Multiply volume by density to get quantity

• For example, to calculate quantity of concrete needed for a slab, multiply slab dimensions by density of concrete
