Question

How many cube of side 3 cm can be cut from a solid cuboid whose length , breadth and hight are 21cm,9cm and 5 cm respectively​

Answer 1

Answer:

the answer is 35 cubes.

Answer 2

Answer:

35 cubes can be cut

Step-by-step explanation:

In the cuboid,

In the cuboid, length = 21cm

In the cuboid, length = 21cmbreadth = 9 cm

In the cuboid, length = 21cmbreadth = 9 cmheight = 5 cm

In the cuboid, length = 21cmbreadth = 9 cmheight = 5 cmso, vol. = 21 × 9 × 5 cubic cm.

In the cuboid, length = 21cmbreadth = 9 cmheight = 5 cmso, vol. = 21 × 9 × 5 cubic cm.In the cube ,

In the cuboid, length = 21cmbreadth = 9 cmheight = 5 cmso, vol. = 21 × 9 × 5 cubic cm.In the cube ,sides= 3 cm

In the cuboid, length = 21cmbreadth = 9 cmheight = 5 cmso, vol. = 21 × 9 × 5 cubic cm.In the cube ,sides= 3 cmso, vol.= 3×3×3 cubic cm.

In the cuboid, length = 21cmbreadth = 9 cmheight = 5 cmso, vol. = 21 × 9 × 5 cubic cm.In the cube ,sides= 3 cmso, vol.= 3×3×3 cubic cm.therefore,

no. of cubes can be cut = 21 × 9× 5

3×3×3

now you can get 35 by solving this above problem.

just cut 3 and 21 you will get 7 above. the cut 3×3 and 9 . you will be left with 7×5 that is 35.

HOPE IT HELPS YOU

HAVE A NICE DAY.
