V=900m³
V=L*w*h
V=20*3*w
V=60*w
60*w=900
w=900/60
w=15m

Answer:
False
Step-by-step explanation:
In this question, you roll 3 from the standard die and then add it with the next roll to see if the sums are greater than 4.
From this explanation you can see that you use the result from your first roll for the second event, so we can conclude that the event is dependent.
Imagine if we change the result of the first roll into 5, without adding the second roll we can know that the sum will be greater than 4. The first event result will influence the second event, so it is a dependent event.
Isolate the variable by dividing each side by factors that don't contain the variable.
