I saw the image that should have been included in this problem.
It was a rectangular prism. It can also be identified as a right prism because its bases are aligned one directly above the other and its lateral faces are rectangular.
The image has the following measurements: length = 7 inches width = 5 inches height = 4 inches
volume = length * width * height v = 7 in * 5 in * 4 in v = 140 in³ Choice B i believe.
Yes you could because the obtuse angle is greater than 90 degrees so if the acute angle is inside the obtuse you could get an right angle or an 90 degree angle
