Pyramid Frustum Calculator

Pyramid Frustum Calculator

Calculate the volume, lateral area, and total surface area of a pyramid frustum by entering the top & bottom base dimensions and height.

frustum surface area calculator

A Pyramid Frustum Calculator allows one to estimate the volume, lateral surface area, and total surface area of a truncated pyramid by typing in the top base, bottom base, and height. It is ideal in geometry, engineering, and design, and is designed to give instant and precise results.

frustum lateral area calculator

The Pyramid Frustum Calculator is an online tool that computes the volume, lateral surface area, and total surface area of a truncated pyramid (frustum) using its top base, bottom base, and height. By entering the top base length and width, bottom base length and width, and height, the calculator instantly provides accurate results using standard formulas:

\[ Volume = \frac{h}{3}(A_{1} + A_{2} + \sqrt{A_{1}A_{2}}), A_{1} = \textrm{top base area,} A_{2} = \textrm{Bottom Base area} \]

\[ \textrm{Lateral Area} = \textrm{Sum of trapezoid areas of sides, } \textrm{Total Area} = \textrm{Lateral Area} + A_{1} + A_{2} \]

This tool is useful for students, engineers, architects, and designers who need precise frustum measurements for construction, design, or math problems. The interface is simple, responsive, and requires no installation, delivering instant results while reducing manual calculation errors.

Work, Installation, Input to Output

Work:

  • Accepts top base length & width, bottom base length & width, and height.
  • Calculates top and bottom base areas.
  • Computes volume, lateral surface area, and total surface area.
  • Displays results instantly.

Installation:No installation required; works in any modern web browser.

Input:

  • Top base length (\iota _{1}) & width (\omega _{1})
  • Bottom base length (\iota _{2}) & width (\omega _{2})
  • Height (h)

Output:

  • Top base area
  • Bottom base area
  • Volume
  • Lateral surface area
