Question

Find the Surface Area of the prism please

Answer 1

Answer:

1544 m³

Step-by-step explanation:

surface area = 2 × base + lateral area

 base = (10×20)÷2 = 100

 Lateral area = perimeter × height

                      = (20+14+14)×28

                      =1 344

Final answer :

surface area = 2 × base + lateral area

                     =  2 × 100 + 1344

                     =  200 + 1344

                     =  1544
