What are the dimensions of a modular brick?

The dimensions of a modular brick are standardized to facilitate ease of handling and construction in masonry work. The correct dimensions of a modular brick are typically 7 5/8 inches long, 3 5/8 inches deep, and 2 1/4 inches tall. This specific size has been adopted widely in construction to provide uniformity and compatibility with mortar joints, which often take up an additional 3/8-inch.

This uniformity is crucial in building walls and structures, ensuring that bricks fit together properly, allowing for efficient laying and reducing the likelihood of issues such as uneven surfaces or gaps. The choice listed provides the essential measurements that are consistent with industry standards, making it the correct answer in this context.

Other choices do not correspond to the standard dimensions recognized for modular bricks, which can lead to complications in construction, such as misalignment and increased material wastage. Thus, knowing the proper dimensions is key for any professional involved in masonry and building design.
