Each face of a cube has perimeter equal to 32 cm. Find its surface area and its volume.
Answers
Answer:
The faces of a cube are squares.
Let the side of the square or the cube =a cm
Perimeter of the square =4a=32 cm →a=8 cm
Total surface area of a cube of edge a =6a²
So, the total surface area of the cube of edge a =8 cm is 6(8)² = 384cm²
