Volume of the cuboid (V)=12cm3

Dimensions of new cuboid,

L=2l

B=2b

H=2h

Volume of new cuboid =LBH

                                       =(2l)(2b)(2h)

                                       =8(lbh)

                                       =8V

                                       =8×12

                                       =96cm3

Step-by-step explanation:

Let,

l=length of the first cuboid

b= breath of the first cuboid

h= height of the first cuboid

volume of the cuboid is is 12 cm cube

dimensions of the new cuboid are,

L=2l

B=2b

H=2h

we know that,

volume of the new cuboid = l×b×h

= 2l×2b×2h

= 8(lbh). (since,v=lbh)

=8v

= 8×12. (since,v=12 cm cube)

=96cm cube.
