Question

if r u a genius then prove it by giving the ans of 10,11,12,13 plz ans it urgently and fast i will make her a brainlest

Answer 1

10.Volume of small cuboid=4*3*2=24
Volume of bigger cuboid=8*6*4=192
Then no. of cubes cut=192/24=8

11.First cube=6*6*6=216
Second cube=8*8*8=512
Third cube=10*10*10=1000
Adding all these=1000+512+216=1728
Thus side of new cube=12

12.Dimension of bricks=24*13*5=1560
Dimension of walls=1300*1200*120=187200000
Since there are 4 walls
Then,4*187200000=748800000
Thus no. of required bricks=748800000/1560=480000

13.outer dimension=52*15*6
thickness of box=1.5
then inner dimension=50.5*13.5*4.5=3067.88
