Answer:
B 228h = 912
Explanation:
When trying to find the missing height for volume you multiply length times width.
19x12=228
228 times the height (h) would give you 912.
Put it in an equation and you would get 228h =912
Extra: To find for h you would divide 912/228 and the answer would be 4
The height equals 4
Hope this helps.
