Answer:

hey this is your answer

Step-by-step explanation:

  • Volume of Cube =
  • = 512
  • a = ³512
  • a = 8
  • side is 8 cm
  • total length is 8+8 = 16
  • breadth = 8
  • height = 8

______________*_______________

Find surface area of cuboid

  • Surface area of cuboid = 2 ( lb + bh + hl )
  • 2 ( { 16 x 8} + { 8 x 8} + { 8 x 16})
  • 2 ( 128 + 64 + 128)
  • 2 ( 320)
  • 640 cm²

Answer:

=> Volume of Cube = a^3.

=> a^3 = 512.

=> a = cube 512.

=> a (side) = 8 cm.

=> Total length = 8 + 8 = 16 cm.

=> Breadth = 8 cm.

=> Height = 8 cm.

=> Surface Area of a Cuboid = 2 ( lb + bh + hl ).

=> 2 [ ( 16 × 8 ) + ( 8 × 8 ) + ( 8 × 16 ) ].

=> 2 ( 128 + 64 + 128 ).

=> 2 ( 320 ).

=> 640 cm^2.
