The bottom of a straight prism is a square with a side length of 3. How much is the side area of the straight prism and how much is the total area It's a square with two sides
Because it is a straight four prism, the bottom is a square, everywhere is right angle, very good calculation
Side area = 2 * 3 * 4 = 24
Total area = 2 * 2 * 2 + 24 = 32
