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 width of openings like window, doors.
Height of rectangular opening - (Measured in Meter) - Height of rectangular opening is the height of rectangular portion of opening (doors ,window).
Thickness wall - (Measured in Meter) - Thickness wall is simply width of your given wall.

STEP 1: Convert Input(s) to Base Unit

Length of rectangular opening: 2 Meter --> 2 Meter No Conversion Required
Height of rectangular opening: 2.7 Meter --> 2.7 Meter No Conversion Required
Thickness wall: 0.23 Meter --> 0.23 Meter No Conversion Required

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

Is there any no deductions made?

No deduction is made for the following-
1. Opening each upto 1000sq.cm or 0.1 sq.m [1sq.ft].
2. Ends of beams, posts, rafters, purlins, etc upto 500sq.cm or 0.05 sq.m( 72 sq in) in section.
3. Bed plate, wall plate , bearing of chajjas and the like upto 10cm (4") depth.

Bearings of floor and roof slabs are not to be deducted from wall masonry.

How to Calculate Volume of deduction for rectangular opening?

Volume of deduction for rectangular opening calculator uses Volume for deduction = Length of rectangular opening*Height of rectangular opening*Thickness wall to calculate the Volume for deduction, The Volume of deduction for rectangular opening formula is the volume of masonry/brickwork for rectangular opening that you need to deduct from your actual volume of masonry , because if you will be providing doors, windows, lintels ( of rectangular shape) then you won't be utilising that area in brickwork and hence that volume you will need to deduct to make sure that you don't order material more than you need in construction. Volume for deduction is denoted by V_deduction symbol.

How to calculate Volume of deduction for rectangular opening using this online calculator? To use this online calculator for Volume of deduction for rectangular opening, enter Length of rectangular opening (L_opening), Height of rectangular opening (h_opening) & Thickness wall (t_wall) and hit the calculate button. Here is how the Volume of deduction for rectangular opening calculation can be explained with given input values -> 1.242 = 2*2.7*0.23.

FAQ

What is Volume of deduction for rectangular opening?
