Question

find the maximum number of cubes of sides 3cm that can be cut out of a cuboid of dimension 18cm*12cm*9cm fast reply

Answer 1

let "n" be the number of cubes.
volume of cuboid = volume of cubes *n

lbh = a^3 * n
as per given,
lbh (volume of cuboid ) = 18cm*12cm*9cm = 1944

a^3(volume 1 of cube)= 3*3*3 =27

1944 = 27 *n
n= 1944/27

n=72
thus ,the maximum number of cubes of sides 3cm that can be cut out of a cuboid of dimension 18cm*12cm*9cm = 72 cubes.

hope it helps!!!!!
