Answer 1

Questioñ:

If the total surface area of a cubical tank is 486 square meters , What is the length of one side?

Solutioñ:

• Let s be the side of the cubical tank.

• TSA of the cubical tank = 486 m2

So,

⇒6s2 = 486

⇒ s2 = 486 / 6 = 81

Taking square root both sides, we get

s = 9

Therefore,

The side of the cubical tank is 9 m.
