how do you find height of a rectacular prism when you know the volume and lenght?
Am I wrong thinking you devide?
if V=a·h and A=l·w
lets say area=5cm squared and the volume i already know is 12
V=a·h
12=5·h
would you do 12/5?
thanks!
+9466 volume = area of base * height
V = ah
If you know V = 12 cm3 and a = 5 cm2 , we can say
12 = 5h Divide both sides of this equation by 5 .
12/5 = 5h/5 Any number times five divided by five equals the original number.
12/5 = h
2.4 cm = h Exactly as you said !! 
Now......if you know volume and length , and want to know height, we could say
V = lwh
But...we cannot get a specific solution here because we need to know what the width, " w " is.
