Density = Mass/Volume = 120/(12*10*2) grams/cubic cm = 0.5 g per cc.
The surface area of a cube is calculated using the formula (6a^2), where (a) is the length of one side. For a cube with sides of 2 cm, the surface area would be (6 \times (2 \text{ cm})^2 = 6 \times 4 \text{ cm}^2 = 24 \text{ cm}^2). Therefore, the surface area of a 2 cm x 2 cm x 2 cm cube is 24 cm².
To find the area, we first need to clarify what is meant by the given dimensions, as they appear to represent multiple lengths rather than a single geometric shape. If you are referring to a rectangular prism (cuboid) with dimensions 4 cm, 4 cm, 2 cm, 8 cm, and 6 cm, it would be necessary to identify which dimensions are being used. However, if we consider a cuboid with dimensions 4 cm, 4 cm, and 2 cm, the surface area can be calculated as (2(lw + lh + wh)), where (l), (w), and (h) are the length, width, and height respectively. For 4 cm x 4 cm x 2 cm, the surface area is (2(4 \times 4 + 4 \times 2 + 4 \times 2) = 2(16 + 8 + 8) = 2(32) = 64 , \text{cm}^2).
