Answer 3

being a Right Prism, the trapezium of the face above is Right angled, which means that the Height of the trapezium = 46 cm

Answer 4

using the formula on the website above, the area of the face =
0.5 * 46 * (59 + 75) = 23 * 134 = 3082 cm squared

if you multiply the above area by the length of the prism 120, you'll get the volume in cubic cm.

is this clear or u need help understanding it?
