A rectangular tank 50 cm long, 20 cm wide, and 33 cm high is filled with water to a depth of 12cm. How many more liters of water need to be added to fill the tank?

21 litres

Step-by-step explanation:

1 litre = 1000 cubic cm

The rectangular tank is 50 cm long, 20 cm wide, and 33 cm high.

The tank is in the shape of a rectangular prism.

The volume of a rectangular prism is:

V = l * w * h

where l = length

w = width

h = height

Therefor, its volume is:

V = 50 * 20 * 33 = 33000 cubic cm = 33 litres

The tank is filled to a depth of 12 cm.

The volume of water in the tank is:

V = 50 * 20 * 12 = 12000 cubic cm = 12 litres

Therefore, the number of litres left to fill the tank is:

33 - 12 = 21 litres

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
