Answer:

The total surface area of the given prism is 152 square centimeters.

Step-by-step explanation:

The total surface area is given by:

[tex]A_{T} = 2A_{t} + 2A_{r_{l}} + A_{r_{b}}[/tex]

Where:

[tex]A_{t}[/tex]: is the area of the triangle of the prism (it has 2 triangles)

[tex]A_{r_{l}}[/tex]: is the area of the lateral rectangle of the prism (it has 2)

[tex]A_{r_{b}}[/tex]: is the area of the rectangle base of the prism (it has 1)

The area of the triangle is:

[tex] A_{t} = \frac{bh}{2} [/tex]

Where:

b: is the triangle base = 6 cm

h: is the traingle height = 4 cm

[tex] A_{t} = \frac{bh}{2} = \frac{6 cm*4 cm}{2} = 12 cm^{2} [/tex]

The area of the lateral rectangle of the prism is:

[tex] A_{r_{l}} = x*y = 8 cm*5 cm = 40 cm^{2} [/tex]

Now, the area of the rectangle base is:

[tex] A_{r_{b}} = x*b = 8 cm*6 cm = 48 cm^{2} [/tex]

Finally, the total surface area is:

[tex]A_{T} = 2A_{t} + 2A_{r_{l}} + A_{r_{b}} = 2*12 + 2*40 + 48 = 152 cm^{2}[/tex]

Therefore, the total surface area of the given prism is 152 square centimeters.

I hope it helps you!
