Question

Find the edge of a cube whose surface area is 432 m².​

Answer 1

Answer:

Length of edge of cube is 6√2m

Explanation:

It is given that the surface area of cube is 432m² and we are asked to find the length of edge of cube. We know that the surface area of cube will include it's all 6 face, all have the shape of square. So the formula for finding surface area of cube will be:

Surface area of cube=6×Side²

Put the value of surface area here:

⇒ 432m²=6×Side²

⇒ 432m²/6=Side²

⇒ 72m²=Side²

⇒ √72m²=Side

⇒ 6√2m=Side

So the length of each side of cube is 6√2 metres.
