Question

the volume of a cube is 729 metre cube the total surface area of the cube is

Answer 1

We know that,

Volume of cube = Side^3

=> Side^3 = 729

=> Side^3 = 9^3

=> Side of cube = 9 m

Total Surface Area = 6 side^2

= 6× 9^2

= 6 × 81

= 486 m^2

Answer 2

side cube=729
side=9m
t.s.a=6side sq.
=6×9sq
=6×81
=486msq.
