Answer:
s = 6
Explanation:
To answer this question we have to know the formula for volume: l x w x h
We are given the l (length) and the h (height), this means we are trying to find the w
1) Substitute our values we know into the formula
We know the length and width so this makes our formula 8 x s x 5 = 240!
2) Solve what we have for now
We can see that we can multiply 5 and 8 together so simplify our equation
We are now left with 40 x s = 240
3) Isolate the s
To isolate we simply have to get rid of the 40. Now we can see that the 40 is multiplies to s to get 240. This means that to get rid of it we have to divide both sides by 40
Our answer is s=6!
4) Check our answer is correct
To check our answer we can do 5 x 8 x 6
- 5 x 8 x 6 = 240
- Our answer is correct!
Hope this helps, have a lovely day! :)
