Question

how many cubic blocks of how of wood of side 20 CM can be cut from a block of wood having dimensions of 2m, 80cm,and 40cm​

Answer 1

Answer:

800 cubes

Step-by-step explanation:

edge of cube=20cm

volume=(20)³

= 800cm³

length=200cm

breadth=80cm

height=40cm

volume=l×b×h

=200×80×40

=640000cm³

no.of cubes=volume of Cuboid/Volume of cube

=640000/800

=800cubes

Answer 2

Step-by-step explanation:

lenght of side of cube =20cm

so volume of cube=SXS

20cmX20cm

400cm²

volume of cuboid = lXbXh

2mx80cmx40cm

200cmx80cmx40cm

640000cm²

blocks fitted =volume of cuboid divided by volume of cube

=640000cm²divide by 400 cm²

=1,600 wodden block fitted
