Three metal cubes whose edges measure 3 cm, 4 cm and 5 cm respectively are melted to form a single cube. Find the edge of thenew cube. Also find the surface area of the new cube.

Answer 1

Find volume of three cubes
volume of cube is side^3

3*3*3=27
4*4*4=64
5*5*5=125

then add these that will be the volume of the big cube formed......

27+64+125=216

then find surface area that is TSA (Total surface area)
Formula for TSA is 6a^2
put the values,

6*216*216=2,79,926

I suppose this answer could be.........
