How many pools of lice can be filled with the amount of lice that are now in the schools of Spain?
VARIABLES:
- Number of schoolchildren in Spain (2015) - 4.773.506
- Percentage of children with lice - 1 of 5
- How many lice can have a child in his head? - 30 (approximately)
- Volume of a louse - 6 mm3 (Volume = length x width x height → Volume louse= 3 mm x 2 mm x 1mm= 6 mm3)
- Capacity of a standard pool 30 m3 → 30.000.000.000 mm3 (30000 l )
CALCULATIONS:
So, with all this factors that affect our small investigation we have to do some calculations.
First of all, we need to know how many children have lice in our country:
- Number of schoolchildren / 5 → 4.773.506/ 5= 954.701 children with lice
Then , we have to calculate the number of lice that (approximately) exist in our schools:
- Number of children with lice x average of lice per child → 954.701 x 30 = 28.641.030 lice in Spanish schools ( in total)
And finally we must know the total volume that occupied all these lice:
- Number of lice in Spanish schools x Volume of the louse → 28.641.030 x 6 mm3 = 171.846.180 mm3 (volume that occupied the lice)
With this new data, now, we can answer the main question.
If we have a capacity of 171.846.180 mm3 we can fill a pool with the same capacity or volume. In other words, we can fill a pool of 0.172 m3 completely.
How many pools of lice can be filled with the amount of lice that are now in the schools of Spain?
Answer: One pool of 0’172 m3 ( 172 l )
