Answer:
hey this is your answer
Step-by-step explanation:
- Volume of Cube = a³
- a³ = 512
- a = ³√512
- 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.
