Answer:
1620 m³
Explanation:
To find the answer, we simply have to multiply the three values by three, and then multiply those new values together. 5 x 3 = 15, 4 x 3 = 12, 3 x 3 = 9, Multiply 15 x 12 x 9 and you get 1620.
(P.S. Make sure you put meters cubed [m³]! Some teachers are very picky about that.)
