Find the surface area of the prism

The picture is too blurry. could you submit a new photo?

Step-by-step explanation:

Below!

Step-by-step explanation:

First, find the area of the two triangle using the formula A= bh/2

A = 10 x 12 / 2

   = 120 /2

   = 60 cm^2 each triangle

Now find the area of the two side areas using the formula A = bh

A = 3 x 13

   = 39 cm^2 each

Find the area of the base strip using A = LW

A = 10 x 3

   = 30

Finally you need to add up all the areas to get the surface area

SA = 60(2) + 39(2) + 30

     = 120 + 78 + 30

     = 228 cm^2

Hope this helps, good luck!
