A rectangular water tank is 90cm​

Answer 1

Correct question $\rightarrow$

⠀⠀⠀⠀⠀⠀

A rectangular water tank is 90cm wide and 40cm deep. If it can contain 576 litres of water, what is its length?

⠀⠀⠀⠀⠀⠀⠀

Answer $\rightarrow$

⠀⠀⠀⠀⠀⠀⠀

Let the length of the rectangular tank be l cm.

Given its width is 90 cm, and depth is 40 cm.

Now the volume of the rectangular tank is 90×40×l=3600l cm³

⠀⠀⠀⠀

Given it can hold 576 litres =576,000 cm³ of water.

⠀⠀⠀

Then,

⠀⠀⠀

3600 l= 576,000

⠀⠀⠀⠀

Or l = $\frac{5760}{36}$

⠀⠀⠀⠀

Or l = 160
