Question

What is the largest number of pipes of the shape of right circular cylinders with length 10 cm and radius 1 cm that can be fitted into a box, all of whose sides are 20 cm in length?

Answer 1

largest number of pipes = Volume of box / Volume of cylinder

Volume of box (cube) = 20³ = 8000 cm³

Volume of cylinder = πr²h = 3.14 * 1² * 10 = 31.4 cm³

So, largest number of pipes = 8000 / 31.4 = 254.777...

Answer is 254 (Since number of pipes will always be integer.)
