Total Surface area of cube=6l²
864cm²=6l²
(864/6)cm²=l²
144cm²=l²
√144=l
12cm=l
Volume of cube=l³
=12³
=1728cm³
864cm²=6l²
(864/6)cm²=l²
144cm²=l²
√144=l
12cm=l
Volume of cube=l³
=12³
=1728cm³

surface area of cube = 6a²
so
6a² = 864
a² = 144
a = √144
a = 12
then
volume of cube = a³
= 12³
= 1728 cm³
so
6a² = 864
a² = 144
a = √144
a = 12
then
volume of cube = a³
= 12³
= 1728 cm³
