Q13. A big cuboidal box made of cardboard has dimensions 63 cm x 35 cm X 21 cm. How many
small cubes with side 7 cm can be placed in the box?​

Answer 1

Answer:

Step-by-step explanation:

To determine the number of cubes to be placed in the cuboidal box, we need to find the volume of each object.

1) For volume of cuboidal box,

Length = 63cm, Breadth = 35cm, Height = 21cm

Volume of cuboid = L x B x H

= 63 x 35 x 21

= 63 x 735

= 46305cu.cm

Therefore, volume of box is 46305cu.cm

2) For, volume of cube,

Side = 7cm

Volume of cube = side^3

= (7)^3

= 343

Therefore, volume of cube is 343cu.cm

No. of cubes to be placed in box

= Volume of box / Volume of cube

= 46305 / 343

= 135

Therefore, 135 cubes can be placed in such a box.
