Answer Key:
The base of each tower is 625 m^{2}, with the exception of the red tower, which has a base of 1250m^{2}.
To find the height, you must multiply the number of floors by 4.
Color

Height

Volume

Blue

50 x 4 = 200 m

200 x 625 = 125,000 m^{3}

Green

66 x 4 = 264 m

264 x 625 = 165,000 m^{3}

Gold

90 x 4 = 360 m

360 x 625 = 225,000 m^{3}

Red

108 x 4 = 432 m

432 x 1250 = 540,000 m^{3}

There are 2 blue towers = 250,000 m^{3}
There are 2 green towers = 333,000 m^{3}
There are 3 gold towers = 675,000 m^{3}
There is 1 red tower = 540,000 m^{3}
Total volume: 1,798,000m^{3}
