Leon's new tank will collect water off the roof of his house which is 160m2. He intends to use the water for watering the garden and washing his car. Leon estimates that he will use approximately 80L of water per day. If the average rainfall in June is 70mm, how full will the tank become by the end of June if it is empty in the start?
- 1mm rain per m2 = 1L water
Note: Please show working out.
Thank-you so much.

Average rain collected per day = 70mm × 160m^2 = 11200L. Using 80L per day leaves him with 11120L per day, for a total of 11120 × 30 = 333,600L by the end of June - but since this is likely to be much bigger than his tank's capacity, the tank will simply be full.
In reality, it'd be very unusual to collect rain from the whole roof area.

new tank: 160m3
80L of water per day = 80L x 30 days = 2,400L
June = 30 days
rainfall in June is 70mm = 70L x 30 days = 2,100L
Answer= 80L

(70)(160) - (30)(80) = 8,800 L
