<h2>Answer:</h2>

720000 liter

<h2></h2><h2>Step-by-step explanation:</h2>

$Known:\ a=10\ m,b=9\ m,h=8\ m.$

$Because:\ V=abh\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ (Volume\ caculation\ formula)$

$Thus:\ V=10\times9\times8=720\ m^3$

$Because\ 1\ m^3=1000\ L\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ (unit\ conversion)$

$Thus\ 720\ m^3=720000\ L$

A bag contains 135 marbles some white and some transparent. The ratio of white marbles to transparent ones is 3 : 6. How many wh

Setler [38]

Answer:

Number of white marbles in the bag = 45

Step-by-step explanation:

Total number of marbles in the bag = 135

Ratio of white marble to transparent ones = 3 : 6

Let number of white marbles be $=3k$

Then number of transparent marble will be $=6k$

Total number of marbles will be $=3k+6k=9k$

So we have.

$9k=135$

Dividing both sides by 9.

$\frac{9k}{9}=\frac{135}{9}$

∴ $k=15$

∴ Number of white marbles in the bag = $3k=3\times15 = 45$
