Metal spheres, each of radius 2 cm are packed into a rectangular box of dimensions 16 cm x 8 cm x 8 cm. When 16 spheres are packed in the box, it is filled with preservative liquid. Find the volume of this liquid to the nearest integer, [use π =3.14]
Given, dimensions of the rectangular box = 16 cm x 8 cm x 8 cm
∴ Liquid take the vacant space after packing 16 spheres in the box.
∴ Volume of liquid = Volume of the rectangular box-Volume of 16 spheres.
