Question

How many pieces of plywood is 0.45 cm thick, are required to make a pile 2.43 m high

Answer 1

thickness of each plywood=0.45cm
height of a pile required=2.43 m
=>1 cm=10 mm
=>0.45 cm=4.5 mm
=>1 mm = 100 cm
=>2.43 m = 243 cm
=>1 cm = 10 mm
=>243 cm= 2430 mm
therefore, thickness of plywood =4.5 mm
=height of pile =2430 mm
total plywood required=2430/4.5
                                       =540.   {answer}
