The perforated gypsum lath has one hole of 3/4 inch diameter for each how many square inches?

Explanation:
Perforated gypsum lath is laid out in a regular grid, and the density is set by how far apart the holes are. The standard pattern spaces holes 4 inches apart in both directions, so each hole covers a 4 inch by 4 inch area. That’s 4 × 4 = 16 square inches per hole. The hole’s 3/4 inch diameter matters for how the plaster grips, but the spacing defines how many square inches correspond to each hole. So one hole corresponds to 16 square inches.
