Chapter Overview
A brick is a cuboid: it has 6 rectangular faces, 12 edges, and 8 corners.
Building with Bricks develops spatial thinking through brick walls, floor patterns, and rectangular arrangements. Learners study the faces of a brick, identify repeating bonds, and count bricks arranged in rows and layers.
Brick Shapes and Views
- A brick has three pairs of equal opposite faces.
- Its top, front, and side views are rectangles of different sizes.
- A wall is stronger when vertical joints do not form one continuous line.
- A brick pattern may repeat after one row, two rows, or a turn.
Counting Bricks
- Bricks in one layer = number in each row × number of rows.
- For equal layers, total bricks = bricks per layer × number of layers.
- Half-bricks can complete staggered rows at wall ends.
- Look for the smallest unit that repeats before extending a pattern.

Count a Brick Stack
A stack has 4 bricks in each row, 3 rows in each layer, and 2 equal layers. How many bricks are used?
- 1One layer has 4 × 3 = 12 bricks.
- 2There are 2 equal layers.
- 3Multiply 12 × 2 = 24.
Answer
24 bricks
Key Points to Remember
- ✓ A brick is a cuboid
- ✓ Different views of a brick are rectangles
- ✓ Staggered joints strengthen walls
- ✓ Use rows and layers to count efficiently
Exam Tips
- • Mark one repeating part of a pattern
- • Count complete rows before partial bricks
- • Label rows, columns, and layers separately
