Packs = 25

Length = 10

Breadth = 10

Height = 4

Spheres of radius = 6

Mass = 500

Volume of Cuboid = l * b * h

Volume of Cuboid = 10 * 10 * 4

Volume = 400

Density = Mass / Volume

Density = 500 / 400

Density = 1.25

radius = 6

volume = (4/3) * PI * 6 ^ 3

volume = 26

Total Volume of Clay = Number of packs * Volume of a single cuboid clay

Total Volume of Clay = 25 * 400

Total Volume of Clay = 10000 cu.units

Number of spheres = Total Volume / Volume of a Sphere

Number of spheres = 10000 /

A solid which has six rectangular faces at right angles to each other.
