Question

In a stack , there are 90 sheets, each of thickness 0.0015 dam and 120 papers, each of thickness 0.00018 dam.Find the total thickness of the stack in centimetres​

Answer 1

Answer:

3510 cm

Step-by-step explanation:

because

0.0015 dam = 15 cm

:. thickness of first stack = 90 x 15

                                        = 1350 cm

0.0018 dam = 18 cm

:. thickness of second stack = 120 x 18

                                               = 2160

:. total thickness = 1350 + 2160

                           = 3510 cm
