Question

volume of cube is 729 M cube what is the length of side of cube ​

Answer 1

side of cube =

$\sqrt[3]{729}$

= 9 m

Answer 2

Answer:

Step-by-step explanation:

1) let the edge of the cube = a cm

volume(v)= a^3

a^3 = 729

a^3 = (9cm)^3

a = 9cm

2)

lateral surface area = 4 a^2

= 4* 9^2

= 4* 81

=324cm^2

total surface area = 6a^2

= 6* 9^2

= 6*81

=486 cm^2
