Calculating the Number of Colored Glass Pieces in the Stained Glass Window

To calculate the number of colored glass pieces in the stained glass window, we can use the given information about the quantities of different shapes of glass pieces.

Given: - 30 pieces of triangular glass - The number of square pieces is 4 times the number of triangular pieces - The number of rectangular pieces is 40 less than the number of square pieces

Let's calculate the number of colored glass pieces in the stained glass window step by step.

1. Number of Triangular Pieces: - Triangular pieces = 30

2. Number of Square Pieces: - Square pieces = 4 * 30 = 120

3. Number of Rectangular Pieces: - Rectangular pieces = 120 - 40 = 80

4. Total Number of Colored Glass Pieces: - Total = Triangular pieces + Square pieces + Rectangular pieces - Total = 30 + 120 + 80 - Total = 230

So, the stained glass window contains 230 pieces of colored glass in total.

This calculation is based on the given information and the mathematical operations performed to derive the total number of colored glass pieces in the stained glass window.
