How thick is an impregnated sheet?

1. .1 mm

2. .25 mm

3. .5 mm

4. 1 mm

The correct answer is: .25 mm

An impregnated sheet is typically used for projects that require great stiffness and durability. Therefore, it is typically thicker than standard sheets of paper, which usually range from 0.07 mm to 0.18 mm in thickness. Option A (.1 mm) and Option D (1 mm) fall outside of this range and would not be considered appropriate thicknesses for an impregnated sheet. Option C (.5 mm) is also a possibility but is on the higher end of the range and may not be necessary for all projects. Option B (.25 mm) is a good balance between thickness and cost, making it the most appropriate choice for most projects.
