Penyelesaian:

Kawat nya busa di buat seperti tabung dengan ukuran:

T=1m=100cm

r=7cm

----------------------------------------

V=Πr²×t

V=22/7×7×7×100

V=22×7×100

V=154×100

V=15.400cm³

----------------------------------------

15.400cm³÷1.000.000

=0,0154m³

----------------------------------------

100×0,0154

=1,54gram
