Most Cucumber Plants produce up to 10 Cucumbers per plant.
So if you have more than one person in your household you should grow around 3 cucumber plants per person in your household to have enough cucumbers for everyone.
Some cucumber plants may only produce 7 or 8 cucumbers depending on how healthy the cucumber plants are and how well taken care of the cucumber plants are.
Some variety of cucumbers such as the Heirloom cucumber plant produce less and only around 2 to 3 lbs of cucumbers per plant.
