Question

the volume of a cube is 729 cm³. Find its surface area.​

Answer 1

Step-by-step explanation:

cube

solve for surface area

A≈486cm²

v=729cm³

using the formula's

A=6a²

V=a³

solving for A

A=6v⅔=6.729⅔≈486cm²

Answer 2

Step-by-step explanation:

Volume of a cube =

${side}^{3}$

V=side*side*side

729=(side)cube

(Side) cube =729

Side =

$\sqrt{729}$

27*27

Side =27 cm

Surface area of cube=6*(side)square

=6*(27*27)

=6*729

=4374cm Square
