Impetus describes the kind of force that encourages an action (the impetus behind the project) or the momentum of an action already begun (the meetings only gave impetus to the rumors of a merger).
Materials Needed: The box from the last experiment; a ruler that measures centimeters. Procedure: Measure each side of the box in centimeters. Use the formula for the volume of a box shaped object (V = L x W x H ) to calculate the volume of this box in cubic centimeters. What Happened: Each side was 10 cm long. When you plug the numbers into the formula and do the math, you get:
Likewise, the liter is used as the base unit for volume measurements, usually with liquids or substances that are sold by volume in containers, such as berries. This unit of measurement is abbreviated as dl or dL, in contrast with the decaliter, which is written as dal or daL to avoid confusion.
