into a big cube. Find its total surface area.
pls answer it
it's urgent ​

Answer 1

Answer:

Answer:here it is

Answer:here it is Step-by-step explanation:

3 cubes are recasted

volume of 1st cube = 6 ^3= 216cm^3

volume of 2nd cube = 8^3 = 512 cm^3

volume of 3rd cube = 10^3 = 1000cm ^3

total volume = 1728cm ^3

FUN FACT (1728 IS RAMAJUNAM NUMBER ITS A RARE NUMBER)

thus volume of being cube = 1728 cm^3

thus sides of big cube 3√ 1728 = 12

therefore total surface area of big cube = 6a^2

=== 6*144 = 864 cm^3
