Question

A cuboid having 12 cm 8cm 3 cm howcmany minimum number of such cuboids will be needed

Answer 1

Answer:

Step-by-step explanation:

The volume of the cuboid = 12 cm × 8 cm × 3 cm

= 288 cu cm

The cube is formed by stacking many such cuboids and it will have side lengths which are multiple of 12, 8 and 3.

The smallest such cube will have a side length of LCM of 12, 8 and 3.

LCM of 12, 8 and 3 -

12 = 2*2*3

8 = 2*2*2

3 = 3

LCM = 2*2*2*3 = 24

The smallest such cube will have side length of 24 and volume (in cu cm) of (24*24*24) cu cm.

Number of cuboids of volume (12*8*3) cu cm that will fit into a cube of volume (24*24*24) cu cm.

= (24*24*24)/(12*8*3)

= 13824/288

= 48 cuboids

Hope it helps you....

Answer 2

23

Step-by-step explanation:

because 12+8+3= 23 may be answered right
