One egg has about 6 grams of protein in it. So with 4 you're looking at 24 grams.
There would be about 18.87 grams of protein in 3 boiled eggs of average size.
Strawberrys are not a source of protein it is a source of Carbohydrate.
There is no protein in cardboard. If you want protein, you can find it in meat, fish, eggs, legumes. They taste much better than cardboard.
Eggs contain protein but not all protein is made of eggs.

Eggs
Yes they can be. protein shakes have chemicals in them, not just protein eggs are ALL NATURAL protein especially hard boiled eggs.
A 4 oz chicken breast has about 20g of protein. One large hard-boiled egg has 6g of protein. So you'd have to eat 3 hard-boiled eggs to get roughly the same amount of protein.

One egg contains about 6 grams of protein which sounds great, but you have to keep in mind that with that protein, eggs also contain a lot of cholesterol. Even 6 eggs a week could be a high number depending on general health. For example, a diabetic or a person with a predisposition for heart conditions should limit themselves to 4-5 egg yokes a week.
