Question

a cube of side 12 cm is melted down and reshaped into a cuboidal of width 15 cm and length 18 cm . how high is the block​

Answer 1

Given: side of cube =12
Length and breadth of cuboid = 15cm and 18cm respectively
Volume of cube = a cube
= 12 cube
= 12*12*12
= 1728
Volume of cuboid = lbh
1728 = 15*18*h
1728 = 270*h
1728/270 = h
h = 6.4 cm
Therefore height of cuboid form is 6.4cm

Answer 2

Step-by-step explanation:

Given, Shape of a cube=12cm

Length=18 cm and width=15 cm

Volume of a cube= a cube

=12*12*12

=1728

Volume of cuboid= l*b*h

1728 =18*15*h

1728 = 270*h

1728/270=h

h=6.4

Hence, height of a cuboid is 6.4 cm.
