Question

The dimensions of an acid container kept in a lab, that is completely filled with an acid, is as given. If half of the acid from the container is used, how much acid will remain?

• A. 3.2 liters
• B. 2 liters
• C. 2.7 liters
• D. 4.2 liters

Answer 1

The correct option is C 2.7 liters

The given container is in the form of a cuboid.

Length of the container = 15 cm

Width of the container = 12 cm

Height of the box = 30 cm

Volume = length$\times$width$\times$height

= 15 $\times$12$\times$ 30= 5400 cu cm

1000 cu cm = 1 litre

5400 cu cm = 5.4 litres.

Half of the acid is used, hence, $\frac{5.4}{2}$ = 2.7 litres of acid is used.

Therefore, the remaining acid in the container = 2.7 liters.
