How Many Potatoes Are We Going To Get?

Problem:
We planted loads of potatoes at the community farm. How many potatoes are there going to be per family?

What we know:

• There are 20 beds of potatoes with two rows in each bed
• Each bed is about 125 metres long
• The potatoes where dropped by the planter around  35 centimetres apart

Solution:
How much was planted?

• There are 40 rows in total, each 125 metres long
• 40 x 125m = 5000m
• since there is 1000m in a km, we planted 5km of potatoes.

• the distance between potatoes is .35 metres
• 5000m ÷ .35 = 14285
• therefore we planted about 14285 seed potatoes.

Expected crop:
We looked it up and we found the average is 10 potatoes for every seed potato you plant, that means if we plant 14285 seed potatoes then we could expect a crop of 142850 potatoes.

In a book, my dad found that for every metre of seed potatoes you plant you get a crop of 2.5 kg of potatoes.

• 5000m x 2.5kg per metre = 12500kg of potatoes

How many per household:
At the moment there are 50 households but we hope that by harvest time we will have 75 households.

• 12500kg ÷ 75 = 166kg of potatoes
• 142850 ÷ 75 = 1905 potatoes

Conclusion:
If everything works out as we hope, each houshold will get about 1900 potatoes which should weigh about 166kg.
