Question

A cuboid-shaped metal bar of length 8 centimetres, breadth 4 centimetres
and height 4.5 centimetres is melted to form another cuboid that is
6 centimetres long and has a rectangular base area of 18 square
centimetres. What is the height of the new bar?​

Answer 1

Answer:

1.34. or 144/108

Step-by-step explanation:

volume of both the cuboid are equal

so

8x4x4.5=6x18xh

h is height of new bar

h= 8x4x4.5/(6x18)

h = 144/108

= 1.3333333333333

=1.34m
