The volume of a rectangular prism is length x width x height.
You will have to multiply 10.4mm by 5mm by 8mm and the product of that is 416 mm
here is what I think since 2 multiplied by 15 equals 30 you at 35 more to that 30 and you get the answer 60. Is that how it is supposed to go?
Hi!! What do you need help with? Solving the problems? Or understanding them? Also 1-9 is a bit blurry, so if you could retake it and repost it, I could solve for them. :). But if you don’t want to, don’t worry.
If you are asking to simplify, this is what I got. Hope I was able to help
