Maximize usable area: 1.52m x 1.62m using standard plywood dimensions closest to 1.065 aspect ratio, minimizing waste.
Here's how to determine the dimensions of the plywood for maximum usable area:
1. Calculate the usable area:
First, subtract the margin heights from the total height: usable height = 1.92 m - 0.20 m (top) - 0.20 m (bottom) = 1.52 m.
Similarly, subtract the margin widths from the total width: usable width = 1.92 m - 0.15 m (left) - 0.15 m (right) = 1.62 m.
Multiply the usable dimensions to find the maximum usable area: usable area = 1.52 m x 1.62 m = 2.4864 m².
2. Find the aspect ratio:
Divide the usable width by the usable height: aspect ratio = 1.62 m / 1.52 m = 1.065.
3. Determine plywood dimensions:
Choose a standard plywood sheet size close to the aspect ratio. For example, a 2.44 m x 1.22 m sheet has an aspect ratio of 2:1, which is slightly wider than 1.065.
4. Minimize wasted space:
Adjust the plywood orientation to minimize wasted space. For the 2.44 m x 1.22 m sheet, use the 2.44 m length as the height and the 1.22 m width as the usable area (discarding 0.1 m on each side). This gives you a usable area of 2.38 m², slightly less than the maximum but with minimal waste.
