Question

In a stack, there are 90 sheets, each of thickness 0.0015 dam and 120 papers, each of thickness 0.00015 dam. Find the total thickness of the stack in centimetres.​

Answer 1

Given, thickness of each sheet = 0.0015

So, thickness of 90 sheets = 90 * 0.0015 = 0.135

Again, thickness of each paper = 0.00015

So, thickness of 120 papers = 120 * 0.00015 = 0.018

Now, total thickness of stack = thickness of 90 sheets + thickness of 120 papers

= 0.135 + 0.018

= 0.153 dam
