Answer:
Surface area of the prism = 125 sq m.
Step-by-step explanation:
The surface area of the right triangular prism is the sum of area of all its faces.
The area of the two triangular faces =[tex]2x\frac{1}{2} x3 x5=15 m^{2}[/tex]
Area of rectangle on left = 8x3=24 sq m.
Area of center rectangle = 8x5=40 sq m.
Area of rectangle on right = 8 x 5.8 = 46.4 sq m.
Total area =15+24+40+46.4= 125 sq m (Rounded to nearest whole number)
