Question

the cubical water tank is filled in 1296seconds at rate 1 litre per 6 seconds.
i.) calculate internal volume and length of side of tank.
ii.)calculate total internal surface area of tank.​

Answer 1

Answer:

Volume of tank :

6 sec = 1 litre

1296 by 6 = 213

It call fill 213 litre in 1296 sec

Volume = 213 litre ³

Now, length of cubical tank :

Formula = side ³ of volume

So, side³ = 213

=71

71 is length
