Question

there are four cylinders inside a cube and there are 8 such cubes . this 8 cubes are in a cuboid whose length is 64 breadth is 54 and height is 243 metre . find the radius of the cylinder ?​

Answer 1

it can be observed that the volume of the cuboid is equal to the volume of the 8 cubes ....

so. Volume Of Cuboid = 64×54×243 = 839808 m^3

Volume of Each Cube =839808/8= 104976m^3

So Edge Of Cube = Cube root of 104976 = 18root2

so Diameter of each cylinder = 18root2/4

and radius of each cylinder =18root2/8 = 9/2root2
