The number of bricks he originally has is 1800
<h3>How to determine the number of bricks he originally has?</h3>
From the question, we have the following parameters that can be used in our computation:
Bricks used = 2/3 of the bricks he originally
Bricks left = 1200
Since he used 2/3 of the bricks, then he has 1/3 bricks left
This can be represented using the following equation
Bricks left = Proportion of bricks left * Total number of bricks
Substitute the known values in the above equation, so, we have the following representation
2/3 * Total number of bricks = 1200
Multiply both sides by 3/2
Total number of bricks = 1800
Hence, the total number of bricks is 1800
