Volume of Deduction for Rectangular Opening Solution

STEP 0: Pre-Calculation Summary

Formula Used

Volume for Deduction = Length of Rectangular Opening*Height of Rectangular Opening*Thickness Wall
V_deduction = L_opening*h_opening*t_wall
This formula uses 4 Variables

Variables Used

Volume for Deduction - (Measured in Cubic Meter) - Volume for deduction of a particular item (say brickwork, plastering) is the volume that you need to deduct from actual volume of that item of work.
Length of Rectangular Opening - (Measured in Meter) - Length of Rectangular Opening is the width of openings like windows, and doors.
Height of Rectangular Opening - (Measured in Meter) - Height of Rectangular Opening is the height of the rectangular portion of the opening (doors, window).
Thickness Wall - (Measured in Meter) - Thickness Wall is simply the width of the given wall.

STEP 1: Convert Input(s) to Base Unit

Length of Rectangular Opening: 2000 Millimeter --> 2 Meter (Check conversion here)
Height of Rectangular Opening: 2700 Millimeter --> 2.7 Meter (Check conversion here)
Thickness Wall: 230 Millimeter --> 0.23 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_deduction = L_opening*h_opening*t_wall --> 2*2.7*0.23

Evaluating ... ...

V_deduction = 1.242

STEP 3: Convert Result to Output's Unit

1.242 Cubic Meter --> No Conversion Required

FINAL ANSWER

1.242 Cubic Meter <-- Volume for Deduction
