how many blocks

[hardtail]

hi guys i need to work out how many thermalite blocks ill need to inner skin my extension the size of the 2 walls are :2.9mx2.3m with a 2070mmx 900mm door in also 2.3mx2.3m with a 1500mmx900mm window any ideas guys

150 (220mm x 440mm) blocks.

the two walls without doors and windows will take about 150 blocks.
minus 20 for the door and and 14 for the window.
total is 116 blocks

( I am assuming there is only one door and one window in total, not one of each in each wall, if there is one of each in each wall , take another 34 blocks of the total)

thank you both for you input ill order 120 to be safe and i worked out for 578 bricks would you agree please many thanks tim than just goto work out sand and cement

Brick quantity will depend upon whether you are using metric or imperial fellas.

There are 6 metric bricks to one block, less if are using imperial.

The brickwork to pitched roof extensions finishes lower than the blockwork, usually by 1 course of blocks.

2.9 + 2.9 + 2.3 = 8.1m divided by 450mm = 18 blocks long.

2.3 high divided by 225mm = 10.2 blocks high.

18 x 10.2 = 180 blocks less openings (31) = 150 blocks

This was my workings;
Wall one 2.9 x 2.3 =6.67 sqm
wall two 2.3 x 2.3 =5.29 sqm
door 2.3x 0.9 =1.863 sqm
window 1.5 x 0.9 = 1.35 sqm

wall 1+2 =11.96sqm
minus
door+window =3.213sqm
=8.747sq m

block size 440x215 =0.0946sq

8.75/0.0946 =92
adding 12 blocks as half blocks on course height,
it will be about 104 blocks.
As I was originaly calculating two walls at 2.9x2.3 that's how I got to 116.
