Question

The volume of water required to fill half a tank of length 3 m, breadth 4 m and height 5 m is .

• A. 30

Answer 1

The correct option is A 30
We know that, volume of a cuboid
= length $\times$ breadth $\times$ height

Therefore, volume of the tank
= 3$\times$4$\times$5
= 12 x 5
= 60 m${}^3$

For filling half of the tank, we have to take half of the total volume.
So, water required for filling half tank
= 30 m${}^3$
