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

Answer:153 cm

Step-by-step explanation:

1 dam = 1000 cm so 0.0015= 1.5 cm

also 0.00015 dam= 0.15 cm

so 1.5 x 90=135 cm

0.15 x 120=18 cm

add them and the answer is 153 cm

Answer 2

The total thickness of the stack is 153 cm

Step-by-step explanation:

We are given that ,there are 90 sheets each of thickness 0.0015 dam

So, thickness of 90 sheets = $90 \times 0.0015 =0.135 dam$

There are 120 papers , each of thickness 0.00015 dam.

Thickness of 120 papers = 120 \times 0.00015 = 0.018 dam.

So, Total thickness of stack = 0.135+0.018 = 0.153 dam

1 dam = 1000 cm

0.153 dam = 0.153 \times 1000 = 153  cm

Hence The total thickness of the stack is 153 cm
