Problema Solution
Imagine that you have a box shaped protest.The dimensions are 25, 20, and 2. If seven of the food particles per second can enter through each square micrometer of surface area. How many particles can enter in one minute
Answer provided by our tutors
the surface are of the box is S = 2(25*20 + 20*2 + 25*2)
S = 1180 micrometer square
7 of food particles per second enter trough each micrometer
in 1 second there will be 1180*7 = 8,260 particles entering the box per second
in 1 min = 60 seconds there will be 60*8260 = 495,600 particles entering the box.
