To find the surface area of a cube, you can use the following steps:
-
Understand that all sides of a cube are equal: Since the cube has sides of length 4 cm, each side will be 4 cm.
-
Calculate the area of one face of the cube: The area (A) of one face of a cube is given by the formula: \[ A = \text{side}^2 \] Substituting the side length: \[ A = 4 , \text{cm} \times 4 , \text{cm} = 16 , \text{cm}^2 \]
-
Calculate the total surface area (SA) of the cube: A cube has 6 identical faces, so the total surface area (SA) can be calculated using the formula: \[ SA = 6 \times A \] Substituting the area of one face: \[ SA = 6 \times 16 , \text{cm}^2 = 96 , \text{cm}^2 \]
Now summarizing the results:
- One side area: 16 cm²
- Total Surface Area: 96 cm²
So you can fill in the answers as follows:
- One side: [16 cm²]
- Total SA: [96 cm²]
