How many litres of air are in a room that measures $11.0 \mathrm { ft } \times 12.0 \mathrm { ft }$ and has an 7.00 ft ceiling? $\left( 1 \mathrm { in } . = 2.54 \mathrm {~cm} \left( \text { exactly); } 1 \mathrm {~L} = 10 ^ { 3 } \mathrm {~cm} ^ { 3 } \right) \right.$

The volume of the room is:$$V = lwh = (11.0 \mathrm { ft })(12.0 \mathrm { ft })(7.00 \mathrm { ft }) = 924 \mathrm { ft } ^ { 3 }$$Converting to liters:$$V = 924 \mathrm { ft } ^ { 3 } \left( \frac { 2.54 \mathrm { cm } } { 1 \mathrm { in } } ight) ^ { 3 } \left( \frac { 1 \mathrm { L } } { 10 ^ { 3 } \mathrm { cm } ^ { 3 } } ight) = 2.62 	imes 10 ^ { 4 } \mathrm { L }$$Therefore, the correct answer is A.
