Answer:
150 m^2
Step-by-step explanation:
To find the surface area of this shape, find the areas of every face and add them together. This shape has three rectangular faces and two triangular ones.
A rectangle = length * width = 6 * 7 = 42 m^2
A triangle = 0.5 * base * height = 0.5 * 6 * 4 = 12 m^2
3* A rectangle + 2 * A triangle = total surface area
3(42) + 2(12) = SA
126+24 = SA
150 m^2 = SA
You can check this problem by using the formula for surface area of a triangular prism.
