Regular Prism Volume Formula:
From: | To: |
A regular prism is a three-dimensional shape with two identical regular polygonal bases connected by rectangular faces. The volume of a prism is calculated by multiplying the area of its base by its height.
The calculator uses the prism volume formula:
Where:
Explanation: The formula works for any regular prism, regardless of the number of sides in the base polygon, as long as the base area is known.
Details: Calculating prism volume is essential in geometry, architecture, engineering, and various practical applications like determining container capacities or material quantities.
Tips: Enter the base area in square units and height in linear units. Both values must be positive numbers. The calculator will compute the volume in cubic units.
Q1: What's the difference between a prism and a pyramid?
A: A prism has two identical parallel bases connected by rectangular faces, while a pyramid has one base and triangular faces that meet at a common vertex.
Q2: Does this work for irregular prisms?
A: No, this calculator assumes the base is a regular polygon. For irregular prisms, more complex calculations are needed.
Q3: How do I find the base area for common regular polygons?
A: For equilateral triangle: (√3/4)×side²; square: side²; regular pentagon: (1/4)×√(5(5+2√5))×side²; etc.
Q4: Can I use different units for base area and height?
A: No, the units must be compatible (e.g., if base area is in cm², height should be in cm).
Q5: What if my prism is oblique?
A: The same formula applies for oblique prisms, but height must be measured perpendicular to the base planes.
