volume of the cube. =4096 cm³
Step-by-step explanation:
given
area of a face of a cube is 256 cm²
so the side of cube
side² = 256
side = √256
length of side = 16 cm
surface area = 6 × area of one face
surface area = 6× 256 =1536 cm²
volume of the cube = side³
volume of the cube. = 16³
volume of the cube. =4096 cm³
