Question

The total surface area of a cube is 216m. What is the length of each of the cube

Answer 1

Given,TSA of Cube=216m²

But,TSA of a Cube =6a² ; a=length of each side.

→6a²=216
→a²=216/6
→a=√(216/6)

So, The length of each side of a cube = √(216/6)=√36=6m...

So 6m is your answer...

Hope it Helps...

Answer 2

Let each length be x

x×x×x=216
x^3=216
x=6
