Question

the volume of of a cube of 729 cm²
find this surface area​

Answer 1

Step-by-step explanation:

let the edge of cube =acm

Volume =a^ 3

a^3 =729

a^3 =9^3

a = 9 cm

lateral surface area=4×9^2

=324cm^2

Total surface area =6a^2=

= 6×81=486cm^2

Answer 2

Answer:

468 cm^2

Step-by-step explanation:

let side of the cube be a cm then,

volume of cube = a^3

a^3 = 729

a = 9 cm

now surface area of cube = 6a^2

SA = 6.9^2 = 6.81

SA = 486 cm^2
