Answer 1

You want to do l*w*h=v then if you have two answers add them together and you should get the answer. 
    

By the way I'm 11 and in sixth grade going on to 12 and going to be in seventh grade next year

Answer 2

The formula for volume is V = bh Divide by 2 or 1/2
V=b*h/2
 A= 2/h*(top + bottom)
A= 2/12*(7.5 + 5)
A= 2/12*( 12.5)
A=75
V= 75*6
V= 450
