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.
