Question

Diagonal of a cube is 12√6cm.Find surface area and volume of cube.​

Answer 1

Step-by-step explanation:

diagonal of a cube = (√3)a= 12√6

a= 12√6/√3= 12√2

a= 12√2 cm

surface = 6 a×a

= 6×12√2×12√2

=1728 cu cm

so surface area = 1728 square cm

volume= a×a×a

= 12√2×12√2×12√2

=3456√2 cu cm

so volume= 3456√2 cu cm
