Answer: 60
Step-by-step explanation:
V = w h l = 3 x 5 x 4 = 60
Hope this helped, if not i can do the problem again :)!
2x - 3 = 60
(Add 3 to both sides)
2x - 3 + 3 = 60 + 3
2x = 63
(Divide by 2)
2x / 2 = 63 / 2
x = 31.5
You can set up a ratio of side lengths as follows:

Now we just solve for x (by cross-multiplying):


So,
x = 75 units.
