Calculating the Mass of the Brick After Drying and Firing

To calculate the mass of the brick after drying and firing, we can use the information provided.

Given: - The initial mass of the raw bricks = 350 kg - The mass decreased by one-fifth after drying and firing

Calculation: - The mass decreased by one-fifth, which means the remaining mass is four-fifths of the original mass. - Therefore, the mass of the brick after drying and firing = 350 kg * (4/5) = 280 kg.

So, the mass of the brick after drying and firing is 280 kg.
