three solid cubes of sides 1 cm , 6 cm and 8 cm are melted to form a new cube . find the surface area of the cube so formed
explanation : volume of new cube = = edge of new cube = = 9 cm surface area of the new cube = ( 6 x 9 x 9 ) = 486 answer : a ) 486
multiply(multiply(const_3, power(power(add(add(power(1, const_3), power(6, const_3)), power(8, const_3)), const_0_33), const_2)), const_2)
