First, you need to find the area of the lateral surfaces, since each one is a 5cm by 6cm rectangle, all you need to do is multiply to find the area of one of them, and then multiply by 6 to find the area of all 6 sides.
lateral area = 5cm * 6cm * 6
lateral area = 30cm² * 6
lateral area = 180 cm²
Next, you need to find the total surface area by multiplying the area of the base by two and adding that to the lateral surface area.
