Question =“Determine the total surface area of the prism” What is the answer please help

Answer 1

Answer:

392cm^2

Step-by-step explanation:

We need to find the Areas of each face

The front and back share the same area

That means 6+6+32 for one face

Multiply by 2 u get

88cm^2 for the front and back

The Top face has an area of 64cm^2

The left and right faces have an area of 100cm^2

Now for the bottom face

We have 140cm^2

Add them all up

You have

392cm^2

Answer 2

Answer :-

→ Total surface area of prism = 2(Area of front trapezium) + 2(Area of a top and bottom rectangle) + 2(Area of side rectangle)

→ Total surface area of prism = 2[(1/2)(8 + 14)*4] + 2(8*10) + 2(5*10)

→ Total surface area of prism = 4*22 + 2*80 + 2*50

→ Total surface area of prism = 88 + 160 + 100

→ Total surface area of prism = 348 cm² (Ans.)
