Question

Three solid cubes of edges 6cm,10cm and xcm are melted to from A single cube of edge 12cm ,find the value of x​

Answer 1

Answer:

The Answer is 8 cm.

Step-by-step explanation:

Now here comes the step-by-step explanation:-

volume of 1st cube : a³=6³=216

volume of 2nd cube : 10³=1000

volume of 3rd cube: x³

volume of larger cube : 12³=1728

now, 216+1000+x³= 1728

x³ =1728-1216

x³=512

x=8cm

Hope this clears your doubt!! : ]

Answer 2

Hey buddy!

Let the volume of solid cubes of edge 6cm, 10cm,x cm be V1, V2, V3.

Let V be the volume of the cube of edge 12cm..

according to the question,

V1+V2+V3= V

6^3 + 10^3+ x^3 = 12^3

216+ 1000 + x^3= 1758

x^3 = 1758-216

x^3 = 542

x= 8cm (approx)
