Question

- A metallic cuboid has length 12 m,
breadth 9 m and height 8 m. How many
cubes of edge 3 m can be cut out of it?​

Answer 1

▬▬▬▬▬▬▬▬▬▬▬▬

Given :

→ Length (l) = 12 m

→ Breadth (b) = 9 m

→ Height (h) = 8 m

→ Edge of cube (a) = 3 m

To Find :

→ The number of cubes.

Solution :

→ Number of cubes = (volume of a cuboid)/(volume of each cube)

= (l × b × h)/(a³)

= (12 x 9 x 8)/(3³)

= 864/27

= 32

∴ Total number of cubes is 32.
