Acomputer chip 0.32 cm thick is made up of layers of silicon. if the top and bottom layers are each 0.03 cm thick and the inner layers are each 0.02 cm thick, how many inner layers are there? a. 13b. 15c. 16d. 52e. 64

a. 13

Step-by-step explanation:

Choice A = 13 layers is correct answer.

Outer thickness = the top and bottom layer are 0.03 + 0.03 = 0.06 cm thick

Total thickness= 0.32 cm

Inner thickness=  Total thickness - outer thickness = 0.32- 0.06= 0.26 cm

Each inner layer is 0.02 cm thick

No of inner layers = 0.26/0.02= 13 layers

There are 13 layers of 0.02 cm thickness each .
