1. A playhouse has the shape of a rectangular prism with a triangular prism roof. Determine the surface area of the playhouse. Area 1 : $=$ Area 2 : $=$ Area 3: $=$ Area 4: $=$ Area 5: $=$ \[ S A= \] \[ m^{2} \]

Step 1 ：Calculate the area of each face: Area 1 and Area 2: \(A = l * h\), Area 3 and Area 4: \(A = 0.5 * b * t\), Area 5: \(A = l * w\)

Step 2 ：Add all the areas together to find the total surface area: \(SA = 2(l * h) + 2(0.5 * b * t) + (l * w)\)

Step 3 ：\(\boxed{SA = 2lh + bt + lw}\)
