the surface area of rectangular prism:
SA+=2%28Lh%2BLW%2BWh%29
L=84ft
W=50ft
h=4in
in yards:
1foot+=+0.33333333333yards
1Inch+=+0.02777777778yards
L=84%2A0.33333333333yards =>L=27.99999999972yards=>L=28yards
W=50%2A0.33333333333yards =>W=+16.6666666665yards=>W=+16.7yards
h=4%2A0.02777777778yards=>h=+0.11111111112yards=>h=+0.1yards

SA+=2%28Lh%2BLW%2BWh%29
SA+=2%2828yards%2A0.1yards%2B28yards%2A16.7yards%2B16.7yards%2A0.1yards%29
SA+=2%282.8yards%5E2%2B467.6yards%5E2%2B1.67yards%5E2%29
SA+=2%28472.07yards%5E2%29
