Answer: 9cm

Step-by-step explanation:

$7x10=70cmx^{2}$

4(x)=4x

1.) 70+4x=106 (subtract 70 on both sides)

2.)4x=36 (divide 4 on both sides)

10. If 1000 cm = 1 l, find the capacity of the following water tank in litre

Lelu [443]

<h2>Given :</h2>

length = 200 cm

breadth = 150 cm

height = 100 cm

<h2>Solution : </h2>

$\large \boxed{volume = l \times b \times h}$

$200 \times 150 \times 100$

$3000000 \: \: cm {}^{3}$

Through the statement above we have,

$\small\mathrm{1000 \: cm³ = 1 \: \: }l$

$\small\mathrm{1 \: cm {}^{3} = \dfrac{1}{1000} \: }l$

$\small\mathrm{3000000 \: cm {}^{3} = 3000000 \times \dfrac{1}{1000} \: }l$

$\small\mathrm{3000000 \: cm {}^{3} = 3000000 \times \dfrac{1}{1000} \: }l$

$\small\mathrm{ 3000 \: \: litres}$

Is 0.06 greater than 0.0582

Art [367]

Yes, 0.06 is greater than 0.0582.

If we look at the hundreths place, we can see 6 and 5. 6 is greater than 5 which proves that 0.06 is greater.

Best of Luck!
