Question

The total surface area of a cube is 1014 cm square. Find the length of the edge

Answer 1

✌Hey dear.

✌Here is your answer.

We know that total surface area of cube is 6a²

But here the T.S.A given is 1014.

Hence it can be written than

=> 6a²=1014

=> a² =1014/6

=>a²=169

=>a =√169

=>a= 13 cm.

✌Hope it helps.
