Question

find the side of a cube whose surface area is 2058 cm²​

Answer 1

If the side is (a), then it's total surface area = 6a²

It is given that, total surface area of it = 2058 cm²

∴ 6a² = 2058

⇒ a² = 343

⇒ a = (7√7).

So, the side of the cube is of length (7√7) cm.

More:-

• LSA = 4a²
• Diagonal = s√3
• All sides are same.

Answer 2

Answer:

side - 18.52 cm^2

Step-by-step explanation:

surface area of cube - 2058 cm^2

6*side^2 - 2058 cm^2

side^2 - 2058/6 cm^2

side^2 - 343 cm^2

side - square root 343

side - 18.52cm^2
