A cube has 6 squares as the faces of a cube. The area of the square is A = s² where s is the length of the side. Given that area formula, we have: A = (3 centimeters)² = 9 centimeters² So the area of each face of a cube is 9 centimeters²
Area = 6*0.4 = 2.4 square cm
6 cm * 10 cm
Draw it with dimensions of (6 cm) by (3 cm).
A 25 cm cube has all edges with a length of 25 cm. Therefore each face has an area of 25*25 = 625 sq cm. As a cube has 6 faces, the total surface area of the cube is 625*6 = 3750 square centimeters.
