Question

find the volume of cube the surface is 486

Answer 1

SA = 486
6a² = 486
a² = 486 x 1/6
r = 9units
Volume of cube = a³
= 9³
= 729 unitscm³

Answer 2

heya!

here's ur answer...

we know that TSA (surface area) of cube is 6a².

let the side of the cube be a.

therefore 6a²=486cm²

a²=486/6

a²=81

a=√81

a=9

hence the side of the cube is 9cm.

volume of cube=side³

=9×9×9

=729cm³

hope this helps..!

but u have not wrote the unit so I used cm.
