T B
Note: For bricks, you may also enter a brick size
using T B. For example, when building
with standard "face" bricks, store a brick size of
21 square Inches (e.g., 2 1 i i T
B) or store 32 square Inches (e.g., 3 2 i
i T B) for "paver" bricks. This is based
on Modular U.S. brick size of 3-5/8 Inches x 2-
1/4 Inches x 7-5/8 Inches, including 3/8 Inch
mortar = 4 Inches x 2-5/8 Inches x 8 Inches.
