This can't be sec 4 qns isn't it haha?
the total volume of the pool will be = 288m^3
(1.8 x 20 x 8)m
300g => uses 50m^3 water (consumed weekly)
1m^3 water => 300g/50 = 6g of power
288m^3 water = 6g x 288 = 1728g of power/week
1 week => 1728g power
Projected 4 weeks => 4x1728g = 6912g power
6912g > 5000g
One box is not enough for 4 weeks, as it is more than 5000g.
