Calculation of the Mass of the Red Granite Piece

To find the mass of the red granite piece, we need to consider the given information about the masses of the gray, red, and white granite pieces.

Let's assign variables to the masses of the gray, red, and white granite pieces: - Mass of the gray granite piece: G - Mass of the red granite piece: R - Mass of the white granite piece: W

According to the given information: - The total mass of the three granite pieces is 156 kg, so we have the equation: G + R + W = 156.- The gray granite piece is 18 kg heavier than the red granite piece, so we have the equation: G = R + 18. - The red granite piece is 15 kg lighter than the white granite piece, so we have the equation: R = W - 15.

To find the mass of the red granite piece, we can substitute the second and third equations into the first equation and solve for R.

Substituting G = R + 18 and R = W - 15 into G + R + W = 156, we get: (R + 18) + R + (R + 15) = 156.

Simplifying the equation: 3R + 33 = 156.

Subtracting 33 from both sides: 3R = 123.

Dividing both sides by 3: R = 41.

Therefore, the mass of the red granite piece is 41 kg.
