Question

A big cube has each portion of 44 cm. Tiny cubes of 4 cm portion each are cut from
that. Then how many tiny cubes will be formed that are surrounded by at least one
cube ?
(1) 888
(2) 729
(3)
164
(4) 33​

Answer 1

Answer:

Number of cubes formed=volume of big cube/volume of tiny cubes

all sides of a cube are equal

let side be a

and volume=a×a×a=a³

so volume of big cube=44×44×44=85,184cm³

and volume of tiny cube=4×4×4=64cm³

85184/64=1331

but I am unable to understand what do you mean by at least one cube
