Math question down below

Answer 1

For volume of a rectangle your formula would be: l x w x h

So here is how you would do this problem:
V= l x w x h
V= 15.5 (same as 15 1/2) x 10.25 (same as 10 1/4) x 12 
V= 1906.5 inches cubed or 1906 1/2 inches cubed

So your answer would be the third one. 

Answer 2

Okay volume = length × width × height.

So, Volume = 15.5×10.25×12

Volume = 1906.5
