Getting confused please help me.

if 30kg of material covers 1.65 m2 at 15mm.

how thick in mm will 1 square mtr be if i use 33kg

 

[TonyM]

27.22mm

 

[theblones]

tell me how you worked it out my brother

Here's the maths.

1m2 needs 18.18kg of material @ 15mm depth = 1/1.65 x 30.

33/18.18 = 1.815, so you are using 81.5% more material for your 1m2.

15 x 1.815 =27.225

So actually it's 27.23 mm rounded to 2 d.p.

Hope your tape measure is accurate.
