Question

how many wooden cubical blocks of side 20cm can be cut from a cuboidal block of wood of size 5cm × 160cm × 80cm​

Answer 1

Answer:

8 cubes

Step-by-step explanation:

Number of Cubes = (Volume of wood block) ÷ (Volume of cube)

= (5×160×80) ÷ (20×20×20)

= 8 cubes

Answer 2

n*(volume of one cubical block) = volume of cuboid

=>n(20*20*20)=5*160*80

=>n=(5*160*80)/(20*20*20)

=>n=8

8 cubical blocks can be cut out...

But practically, no cube can be cut out.. Because height of Cuboid is 5cm but cube side is 20cm. How can we get 20cm cube from 5cm Cuboid? Silly Right....
