surface area of cube=6x²=864m²
therefore,
x²=864/6=144
therefore,
x=√144=12 m
so, the volume if cube =x³=1728 m³
therefore,
x²=864/6=144
therefore,
x=√144=12 m
so, the volume if cube =x³=1728 m³

given surface area =864
so ,
a^2=864÷6
a^2=144
a=√144
a=12
now volume of cube is a^3
= 12^3
=1728
so ,
a^2=864÷6
a^2=144
a=√144
a=12
now volume of cube is a^3
= 12^3
=1728
