Question

please answer this ​

Answer 1

Answer:

height is 5cm

Step-by-step explanation:

we know that

length breadth and height of the block in first case are

4 5 and 6 resp.

in second case the dimensions are

8 3 and h

so now

4×5×6 = 8×3×h

so it will be

120 = 24×h

so

height will be

5

Answer 2

Answer:

5cm

Step-by-step explanation:

Let the height after melting be x

If the block is melted and made of different magnitude, the area will remain same

Area of cuboid = l×b×h

4×5×6 = 8×3×x

120 = 24x

x = 120/24

x = 5

Height after melting the block will be 5 cm.
