Question

f. If the thickness of a pile of 15 tin sheets is 54 mm, how many tin sheets will be
there in a pile that is 72 mm thick?​

Answer 1

Answer:

20 sheets

Step-by-step explanation:

Given,

thickness of 15 tin sheets = 54 mm

using unitary method,

thickness of 1 sheet = 54/15

                                 = 3.6 mm

∴ no. of sheets in 72 mm thick pile = no of sheets/ thickness of one sheet

                                                          = 72/3.6

                                                          = 20 sheets
