employed: 1,312,700 people
- employed : 100% - 5.6% = 94.4%
employed people:
$50 per square meter
the surface area of a rectangular prism with Legnth Widh and Height is
SA=2(LW+LH+WH)
so
L=16
W=12
H=8
SA=2(16*12+16*8+12*8)
SA=2(192+128+96)
SA=2(416)
SA=832 square meters
at 50 per square meter
so times 832 by 50 to get 41600
the cost is 41600 monies
