The safe level of radon gas at home is 4X10e12 Ci/L or less. If you measure radon levels in the basement what is the maximum number of Ci that could be safe to find in a basement with dimensions of 12 ft x 15 ft x 6 ft?

12 ft = ? cm
15 ft = ? cm
6 ft = ? cm.
volume basement = length cm x width cm x height cm = volume in cubic cm = cc.
!000 cc = 1 L
4E12 Ci/L x volume basement = ?
Note: I believe your notation of 4 x 10e12 is redundant. I think you write
4E12 OR 4 x 10^12 but not both. 
thanks a lot big help
