Answer:

$\Huge \boxed{\mathrm{2 \ cm }}$

Step-by-step explanation:

$\sf Volume \ of \ cuboid= length \cdot width \cdot height$

The width is 8.5 cm.

The height is 13 cm.

The volume is 221 cm³.

$221 = l \cdot 8.5 \cdot 13$

Solving for $l$

$221=l \cdot 110.5$

Dividing both sides by 110.5

$2=l$

The length is 2 cm.

Find the infinite sum of 10,5,2.5,1.25...

____ [38]

Notice this is a geometric progression since each number multiplied by some factor equals the next number in the sequence, in this case,

$10 \times r = 5 \Rightarrow r=0.5$

Then by applying the formula for sum to infinity of a geometric progression,
$S_\infty = \frac{a}{1-r} = \frac{10}{1-0.5} = 20$
