0 cm3 (cubic centimeter). 0 cm3. 0 cm. 0 cubic centimeter. FIGURE 3: The volume (V) of any regular solid is equal to the area of the base (l × w) times the height (h); consequently, V = lwh. As an example: 2 cm × 2 cm × 2 cm = 8 cm3. Notice that each layer contains 4 cubic centimeters. There are two layers for a total of 8 cm3. The volume you swept out was a cube, because its length, width, and height were all equal. 0 cm in length, width, and height. What is the volume of the cube? 0 cm2. As shown in Figure 3, the volume of any regular solid is given by the formula: Volume = area of base (length × width) × height, or V = lwh.

Capillary action may sound as if it is about the circulation of blood in the body and, indeed, it helps the pumping action of the heart. However, capillary action is more than that. Capillary action moves water through narrow spaces. It moves water with dissolved nutrients through the soil so that plants can grow. It helps carry tree sap to where it is needed in a tree, even up to its very top. It is capillary action that helps a paper towel wipe up a spill and helps materials to become wet. Capillary action depends on cohesion, adhesion, and surface tension—all three of them.
