4 cm
The question cannot be answered. A square metre is a measure of area not of volume. A block of lead, with an area of 1 square metre could be a few atoms thick or several metres thick. Their weights will differ considerably.
assume 4" thick. 4"x48"x192"/(36"x36"x36") = 0.79 yards 36" in a yard
2 cm (3/4") or 3 cm (1-1/4").
A 4 mil thickness is four thousandths (0.004) of an inch.
Typically, a code 6 lead would weigh around 0.6 ounces per foot.
Code 7 (3.15mm thick) is used for Vertical Cladding, pamet Boxes, Gullys and gutters. Code 8 (3.5mm thick) is used for pampet boxes, gullys and gutters

a thick layer of lead
A sheet of lead needs to be at least 1 cm thick to block gamma radiation effectively. Thicker lead sheets can provide even greater protection.
Gamma radiation can only be stopped by a thick lead sheet or very thick concrete due to its high energy and penetrating ability. Lead and concrete are dense materials that effectively absorb and attenuate gamma rays, reducing their harmful effects on living organisms.
