Question

Plzzzz help me quick

Answer 1

Answer:

Step-by-step explanation:

Volume of cube = 512 cubic units

Side³ = 512

$Side =\sqrt[3]{512}=\sqrt[3]{8*8*8}\\\\\\Side = 8 \ unit$

Surface area of cube = 6a² = 6*8*8 = 384 square units

Answer 2

Answer:

∴surface area = 384 unit^2

Step-by-step explanation:

volume =512 unit^3

formula for cube volume is a^3 where a is the length and we know all the length in cube is similar

a^3 = 512

a=8

∴a = 8

∴surface area of cube formula : 6a^2

6 * ( 8 )^2

384 unit^2

hope this helps and appreciate if u mark this as brainliest answer
