Question

how many cubes of side 3 cm can be cut from a solid cube whose Length breadth and height are 21 cm 9 cm 15 cm​

Answer 1

Answer:

Given:

Cuboid Dimensions = 21×9×15 (in cm)

Cube Side: 3cm

Step-by-step explanation:

Total number of cubes that can be cut from this cuboid can be given by:

(No. of object)(Volume of object) = (No. of object)(Volume of object)

Volume of cuboid = lbh

=21×9×15

Volume of cuboid = 2835cm³

Volume of cube = a³    (a is side of the cube)

=3³

Volume of cube = 27cm³

Let number of cubes in this cuboid be x, then

(x)(27) = (1)(2835)

x = 2835÷27

x = 105

No. of cubes in this cuboid = 105.
