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.

If x-y = 40 and x+y = 70, then what is the value of x squared -y squared ?
OlgaM077 [116]

Let's see what to do buddy...

____________________________

Reminder:

(a + b)(a - b) =  {a}^{2} -  {b}^{2}

So we need to just Multiply above equations like this :

x + y = 70

x - y = 40

(x + y)(x - y) = 70 \times 40

{x}^{2} -  {y}^{2} = 2800

____________________________

And we're done.

Thanks for watching buddy good luck.
