Question

Ametalic cuboid has length 12 m breadth 9 mandheight 8 mHow manycubes of edge 3 mcan becut out of it?

Answer 1

✬ 32 cubes can be cut out of the metalic cuboid. ✬

Step-by-step explanation:

➔ Volume of cuboid = lbh cubic unit

• Length of cuboid = 12 m
• Breadth of cuboid = 9 m
• Height of cuboid = 8 m

➔ Volume of cuboid = 12 × 9 × 8 m³

➔ Volume of cuboid = 864 m³

Finding the volume of cube,

➔ Volume of cube = a³ cubic unit.

• a = 3 m

➔ Volume of cube = 3³

➔ Volume of cube = 3 × 3 × 3

➔ Volume of cube = 27 m³

Now,Finding how many cubes can be cut of it,

➔ No.of.cubes can be cut out = Volume of cuboid/Volume of cube

• Volume of cuboid = 864 m³
• Volume of cube = 27 m³

➔ No.of.cubes can be cut out = 864/27

➔ No.of.cubes can be cut out = 32 cubes
