1.)choose the following

b.)160
c.)400
d.)320

2.)choose the following

b.)1,040
c.)448
d.)1,200

1 is 400. (Volume = length x width x height) (4 x 5 x 20 = 400). Not sure about the second question. If you’re trying to find the volume of the whole figure then I assume you would just add the first two (400 plus 128) (528), but there is no answer choice for that.

)because it's going in order of the math sign

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
