The formula for the volume of this shape is: length * width * height/2
Knowing this, we can set up this equation:
[tex]576= \frac{8*8*x}{2} [/tex]
Now, we can solve for x. I will start by multiplying the 8s and then divide both sides by two.
[tex]1152=64x[/tex]
Next, we divide both sides by 64 to find x.
[tex]x = 18[/tex]
So, x is equal to 18 cm.
