Volume of a Trapezoidal Prism Calculator

Your details

The longer of the two parallel sides of the trapezoidal cross-section.
m / cm / mm
The shorter of the two parallel sides of the trapezoidal cross-section.
m / cm / mm
The perpendicular distance between the two parallel bases of the trapezoid.
m / cm / mm
Length of the left non-parallel side of the trapezoid. Used to compute surface area. Leave 0 to skip surface area.
m / cm / mm
Length of the right non-parallel side of the trapezoid. For an isosceles trapezoid both legs are equal.
m / cm / mm
The distance between the two trapezoidal faces - the depth or length of the prism.
m / cm / mm

Volume = 180.0000 m³

  • The trapezoidal base has an area of 18.0000 m², which multiplied by the prism length of 10 m gives the total volume.
  • The base-to-top ratio is 0.50, a moderately tapered trapezoid.
  • Total surface area is 228.1200 m², useful for estimating material needed to cover or coat this shape.

Next stepUse volume to size containers, earthworks, or structural elements. Pair with surface area to estimate material costs for painting, cladding, or formwork.
