Answer:
8 in
Explanation:
The formula to find the volume of a rectangular prism is l · w · h.
l = ?
w = 6 in
h = 5 in
We know the volume of the following figure is equal to 240 and so we can set up an equation where we solve for l (length).
l · 6 · 5 = 240
To get l by itself, you divide 240 by 6 and then by 5 to get your answer.
l = 8
We can check our work here by multiplying 8 · 6 · 5 which gives us the correct 240.
