To find the volume of the movie theater, we need to calculate the volume of each individual prism and then add them together.
First, let's find the volume of the large square prism in the center:
Volume = side length * side length * height
Volume = 44m * 44m * 20m
Volume = 38,720m3
Now, let's find the volume of one of the smaller square prisms:
Volume = side length * side length * height
Volume = 15m * 15m * 20m
Volume = 4,500m3
Since there are four smaller prisms, we need to multiply the volume of one prism by 4:
4,500m3 * 4 = 18,000m3
Now, we add the volume of the large square prism and the volume of the four smaller square prisms:
38,720m3 + 18,000m3 = 56,720m3
Therefore, the volume of the movie theater is 56,720 cubic meters.
