Question

a cuboid iron bar of lenght 4cm, breadth 5cm and height 6cm is melted to form a cuboid iron bar of lenght 8cm and breadth 3 cm, find its height

Answer 1

Answer:

height=5cm

Step-by-step explanation:

length , breadth & height of the cuboid melted=4cm,5cm,6cm, respectively

volume of the cuboid melted = l*b*h

=4*5*6

'. =120cm

length & breadth of the cuboid form = 8cm ,3cm respectively

height=?

[volume dose not change on changing the shape of object]

volume of cuboid formed = l*b*h

120=8*3*h

h=120/24

h=5

height of the cuboid formed =5cm
