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:
Volume is said to be a derived unit, since the volume of an object can be known from other measurements. In order to find the volume of a rectangular box, for example, one only needs to know the length, width, and depth of the box. Then the volume can be calculated from the formula, V = l Â· w Â· d.he basic unit of volume in the metric system is the liter (abbreviated as L), although the cubic centimeter (cc or cm 3) and milliliter (mL) are also widely used as units for measuring volume.
