Question

How many pieces of plywood each 0.45cm thick are required to make a Pi of 2.43m High

Answer 1

Answer:

Step-by-step explanation:

It takes 1000 sheets to make a pile =0.45 x 1000=450 cm=4.5 meters . So 500 sheets will make , half of that = 2.25 m high . Now 2.43–2.25 =0.18 m or 18 cm thickness more is required , so 18/0.45=1800/45=40 more sheets . So : 500+40=540 sheets are required to make a pile of 2.43 m height . I am of the old vintage group and was perfectly capable of orally dividing 243 cm by 0.45 =24300/45=540 in about ten seconds , but for those who are by now the victims of the calculators , I have suggested this method .
