Answer:
1. 175 cubic ft
2. 42 cubic m
3.140 cubic m
4.216 cubic in
Explanation:
The easiest way too solve this si to split the shapes up into two smaller shapes. For the first one split it into two rectangles, the long rectangle and the smaller rectangle down the bottom right. First we will do the smaller rectangle, multiply 7 by 2 and then multiply that by 5-3 (the bottom length minus the top length) and you get 28. 7(7x3) + 28. This equals 175. Because it is volume the answer is cubic. Repeat theses steps for the other 3 questions and that is how you solve it.
