Step-by-step explanation:
1. 192 cm Squared
2 x 8 x 4 + 8 x 8 x 2
64 + 128 = 192
2. 76 ft Squared
1 x 4 x 2 + 1 x 7 x 2 + 4 x 7 x 2
8 + 12 + 56 = 76
3. 450 yd Squared
15 x 10 x 2 + 15 x 3 x 2 + 10 x 3 x 2
300 + 90 + 60 = 450
4. 510 in Squared
9 x 15 x 2 + 9 x 5 x 2 + 5 x 15 x 2
270 + 90 + 150 = 510
5. 204 mm Squared
1 x 9.3 x 2 + 1 x 9 x 2 + 9 x 9.3 x 2
18.6 + 18 + 167.4 = 204
6. 194 cm Squared
3 x 12 x 2 + 12 x 4 x 2 + 3 x 4 x 2
72 + 96 + 24 = 194
