Could you please help me answer this question. Say that I am laying bricks- If my room is 6ft wide and 24ft long how many 4inch by 8inch bricks will I need?
6 x 24 = 144 square feet.
Given that 1 foot is 12 inches, let's convert the inches to feet.
Brick's width = 4/12 = 1/3 feet
Brick's length = 8/12 = 2/3 feet
Brick's area = 2/9 square feet
So the number of bricks we want is: $\displaystyle 144 \div \frac{2}{9} = 648$ Bricks
