Architect decide to double the width
length increases by 50 percent
height increases by 20 percent
Let L,B,H be length,height and width of rectangular room

therefore new volume V'=L'\times B'\times H'
V'=3.6LBH
new volume is 3.6 times the original

Therefore the region between the lower two magnets has the least force of repulsion.
