Alternatively, you can space the seeds 6 to 10 inches (15.24 to 25.4 cm) apart and thin your seedlings out once they reach 4 inches (10 cm) tall. At that point, you should consider thinning them out so that they are 18 inches (45.72 cm) apart.
Volume - Arcy Art Original Oil Paintings Art Dictionary. Volume is the size, bulk and dimension of a particluar object. It is an object that is usually thick, nontransparent and exists solidly and three-dimensionally in space and it is not flat. In a painting a volume is represented with light and shade and usually in spatial situation to make the nonflatness clear.
Volume is the three-dimensional space a substance occupies. Volumes of many simple shapes can be calculated by using simple formulas. More complicated shapes sometimes can be cut into simple shapes and add the volumes up for the total. Some other complicated shapes can be calculated by integral calculus if a formula exists for the shape's boundary. The volume of even more complicated shapes can be estimated with mathematical methods, such as finite element method. If the density is uniform, the volume of a substance can be calculated from the weight. This volume calculator provides solutions for some of the most common simple shapes.
