Answer:200 cm^2
Explanation:
5 sides, each you have to find the area of and add up to find the surface area.
Surface is the area of the surface of the 3d shape.
Side 1 = 5cm * 11cm = 55cm^2
Side 2 = 6cm * 11cm = 66cm^2
Side 3 = 5cm* 11cm = 55cm^2
All the sides listed above are rectangular, so it's easy. The ones listed below are triangles, which use H * B * 1/2 = A.
Side 4 = (6cm (base) * 4cm (height) *1/2 = 24 * 1/2, which is basically asking for half of 24.) 12.
Side 5 is the same as Side 4.
55 + 66 + 55 + 12 + 12 = 200 cm^2
110 + 66 +24 = 200 cm^2
176 + 24 = 200 cm^2
200 cm^2
