To find the number of square feet, we need to divide the total number of bricks by the number of bricks per square foot.
Number of square feet = Total number of bricks / Bricks per square foot
Number of square feet = 2.967 bricks / 6.9 bricks per square foot
Number of square feet = 0.429347826 square feet
In scientific notation, this is written as 4.29347826 x 10^(-1) square feet.
