Answer: 250m 3
Explanation:
The base multiplied is 50m and the height is 5m, so, 50 x 5 = 250.
The whole question though, is just multiplication.
10m x 5m = 50m
50m x 5m = 250m
Also, since there are 3 different numbers in this problem, the metric unit would be typed as "m 3"
Your answer would be 250m 3
