a rectangle container messuring 20cm by 14.5cm by 10.5cm is filled with filled with water to its brim. if 300cm are drained out of the container, what will be the hight of the water level?

Correction

If 300cm3 are drained out of the container,

Answer:

9.47 cm

Step-by-step explanation:

Volume of the container is given by, V = lwh where l is the length of the container, w is width and h is height.

When filled with water, taking l as 20cm, width as 14.5 cm and height as 10.5cm, the volume of container is

V=20*14.5*10.5=3045 cm3

When 300 cm3 is drained, the remaining volume is 3045-300=2745 cm3

Since the length and width is constant but height varries, the new height will be

20*14.5*H=2745

H=2745/290=9.4655172413793

Rounded off, H=9.47 cm
