Brick Wall Area Problems

Grade 6 Measurement

Key Steps: Convert units to be the same 1st & then divide large area by small area

Key Concept: 1 m² = 10 000 cm²

Wall Size: 7.2 m² Brick Size: 80 cm²

Wall Area Converted: 7.2 x 10 000 = 72 000 cm²

Wall Area of 72 000 cm² divided by Brick Area of 80 cm²

72 000 cm² divided by 80 cm² = 900 bricks (do you see how this could be done mentally?)

Hint: 72 is a product of 8 / 8 is a factor of 72.

Sample Problems:

Wall Size: 4.8 m² Brick Size: 30 cm by 20 cm

Wall Size: 5 m by 10 m Brick Size: 10 cm by 25 cm
