This is a rectangular prism. Its volume is V = (length)(width)(height).
Here, V = (10 cm)(3 cm)(2 cm) = 60 cm^3.
If you already have 4% then that means that the other 48 grams is 96%.
So if you make a proportion with 96/100 and 48/x (x being a stand-in for the answer) you can cross multiply 48 and 100 and divide the end result by 96, which equals 50.
So that means that the answer is 50 grams of protein. Hope this helped!
