If it's 4x8 x 1/2 inch there are 100 in a 'lift'. If the sheets are 5/8 there can be 60 or 80 to a lift. - The manufacturers try to arrange lifts so that building yards fork trucks can easily and safely handle them. A 4x8 x1/2 lift of 100 is approximately 2.5 tons.
About 94 sheets if 4x8.
The recommended drywall screw pattern for securing drywall sheets to a wall or ceiling is to place screws every 12 inches along the edges of the drywall sheets and every 16 inches in the center of the sheets.
The best drywall gap filler to use for filling gaps between drywall sheets is joint compound.
Between the sheets of drywall can be insulation or just hollow.
To determine how many sheets of drywall you need for a 192 sq ft room, first note that standard drywall sheets typically cover 32 sq ft (4 feet by 8 feet). Dividing 192 by 32 gives you 6 sheets. However, it's wise to account for waste and cuts, so purchasing 7 or 8 sheets would be advisable for the project.
You will need at least 14 sheets, depending on shape and height of wall.
4' x 12' = 48 sq ft
You need roughly 94 sheets, however, the shapes of walls and stairs will change that figure slightly.
Drywall is too heavy and large to put on pallets unless you're using smaller length drywall sheets less than 5 feet, which is unheard of unless they're scraps of construction trash or leftover wall board. Drywall in wholesale amounts are delivered by special heavy duty crane/boom trucks that take specialized skilled delivery for upstairs, handcarrying, and are used with special drywall carts that carry 14-17 separate sheets of drywall. Drywall usually come in "bundles" of 2 sheets per bundle. "Bundles" are held together with a pull strip cardboard type tab. Due to the brittleness and heavy weight of drywall, it's very easy to crack or break drywall in half by accident. bundles of weight, thickness, length, and width vary by type of drywall and purpose. I only know because I delivered all the drywall by a boom/crane truck, dolley, and bare hands. JB
The recommended size for the gap between drywall sheets during installation is typically 1/8 inch.
3.5 sheets to cover that.
Impossible to say without knowing how many rooms and what size they are.
