What is the number of bundles of lath needed for the given wall surfaces?

To determine the number of bundles of lath needed for a given wall surface, it's essential to first understand the dimensions of the walls being covered and the coverage area provided by a single bundle of lath. Typically, a standard bundle covers a certain square footage, and you calculate the total square footage of the wall surfaces by measuring their height and width.

After calculating the total wall area, you would divide this figure by the coverage area of one bundle of lath to find the total number of bundles required. If the correct answer is 64 bundles, it suggests that this figure aligns perfectly with the calculations based on the wall surface areas and the coverage provided per bundle, ensuring that a precise amount is needed for the specific project without excess or deficit.

Assessing the other options indicates they may not align with the wall dimensions or coverage calculations. For example, a figure such as 50 bundles may underrepresent the requirement based on the calculated area, while choices like 70 or 80 bundles may either exceed the requirement or not match the precise need established through the calculations. Thus, 64 bundles is the accurate amount needed to efficiently complete the wall surfacing without waste or shortage.
