Question

How many cubes each of edge 20 cm can be placed in a cubical box of length 4 m, breadth 3 m and height 2 m?

A. 3000

B. 4000

C. 5000

D. 1000​

Answer 1

Answer:

Hence the number of cubes = 3000

Step-by-step explanation:

Dimensions of cuboidal box

Length = 4m = 400 cm

Breadth = 3m = 300 cm

Height = 2m = 200 cm

Edge of cube = 20 cm

NO of cubes = Volume of cuboidal box / Volume of cube

= 400 x 300 x 200 / 20 x 20 x 20

= 20 x 300 x 200 / 20 x 20

= 300 x 200 / 20

= 300 x 10

= 3000

Hence the number of cubes = 3000
