Additionally, area applies to only the surface area of a shape, which can account for a single side of a 3D solid. Area only multiplies two sides of a shape to get square units, whereas volume multiplies three dimensions. Volume differs from area, as it measures the inside capacity of a 3D figure.

Volume applies to both solid and liquid capacities, such as units in cubic yards, feet, meters, liters, milliliters and gallons. This refers to a four-sided measure that has a width, length and height of one centimeter. Therefore, when you take the volume of a shape in centimeters, the measurement is cubic centimeters. The unit of measurement for volume is the cubic unit, which represents the three degrees of measurement for 3D solids. Calculating volume depends on the shape of the object you're measuring, as different 3D figures have specific formulas for calculating capacity. It's a metric for 3D modeling and applies to many fields, including engineering and drafting, graphic design and product development. Volume measures the capacity an object can hold. In this article, we explain what the volume of a 3D figure is, describe how it differs from the surface area and show how to calculate the volumes of six types of 3D figures, then offer examples you can reference. If your job requires geometry skills, it might be helpful to learn about calculating the volumes of different shapes. Engineers, graphic designers, animators and other design professionals often measure volume and other metrics to create products and 3D graphics. All the other versions may be calculated with our triangular prism calculator.Geometric concepts like surface area and capacity are important in many career fields. The only option when you can't calculate triangular prism volume is to have a given triangle base and its height (do you know why? Think about it for a moment). Using law of sines, we can find the two sides of the triangular base:Īrea = (length * (a + a * (sin(angle1) / sin(angle1+angle2)) + a * (sin(angle2) / sin(angle1+angle2)))) + a * ((a * sin(angle1)) / sin(angle1 + angle2)) * sin(angle2) Triangular base: given two angles and a side between them (ASA) Using law of cosines, we can find the third triangle side:Īrea = length * (a + b + √( b² + a² - (2 * b * a * cos(angle)))) + a * b * sin(angle) Triangular base: given two sides and the angle between them (SAS) However, we don't always have the three sides given. area = length * (a + b + c) + (2 * base_area) = length * base_perimeter + (2 * base_area).If you want to calculate the surface area of the solid, the most well-known formula is the one given three sides of the triangular base : You can calculate that using trigonometry: Length * Triangular base area given two angles and a side between them (ASA) You can calculate the area of a triangle easily from trigonometry: Length * Triangular base area given two sides and the angle between them (SAS) If you know the lengths of all sides, use the Heron's formula to find the area of the triangular base: Length * Triangular base area given three sides (SSS) It's this well-known formula mentioned before: Length * Triangular base area given triangle base and height Our triangular prism calculator has all of them implemented. A general formula is volume = length * base_area the one parameter you always need to have given is the prism length, and there are four ways to calculate the base - triangle area. In the triangular prism calculator, you can easily find out the volume of that solid.
