Online calculator for grading of two sides of the rectangle and two sides of the retaining plate



App Description

The formula for calculating the pit of the two sides of the rectangle and the two sides of the retaining plate:

\(V=(A+KH)(B+KH)H- \frac {1}{6} KH2(3A+3B+4KH)\)

or

\(V=A \cdot B \cdot H+ \frac {1}{2}KH2(A+B)+ \frac {1}{3}K2H3\)

A, B——Two-way excavation size of the bottom of the pit including the side width working face (m)

H——Pit excavation depth (m)

K——grading slope coefficient

Usage example

Input data:

A—Two-way excavation size of the bottom of the pit including the side width working face: 10

B—Two-way excavation of the bottom of the pit including the side width working face: 56

H-ground pit excavation depth: 7

K—grading slope coefficient: 8

Click "Calculate" to output data

The grading of the adjacent two sides of the rectangle and the volume of the two sides of the retaining plate: 1997.33
