Vere Optical Breadboard 60″ x 16″ x 2″

Vere Optical Breadboard 60″ x 16″ x 2″

The optical breadboard weighs approximately 12 lb per square foot (5.4 kg) regardless of thickness (up to their standard range)

• Area calculation:
  $60\text{in}\times 16\text{in}=960\text{sq in}$
  Since there are 144 sq in in a square foot:
  $960÷144\approx 6.67\text{sq ft}$

• Weight estimation:
  $6.67\text{sq ft}\times 12\text{lb/sq ft}\approx 80\text{lb}$

So a breadboard of that size would weigh around 80 pounds (roughly 36 kg).
