The net of an isosceles triangular prism is shown here. What is the surface area, in square units, of the triangular prism? Three rectangles are shown, one below the other. The middle rectangle has a width of 6 units, and, along each width, is a triangle with a height of 4 units. The length of the lowermost rectangle is 7 units and its width is 5 units.

136 units2

98 units2

94 units2

129 units2

136 units²

Step-by-step explanation:

Because the prism is isosceles triangular then the top rectangle=7 X 5 as well.

The big rectangle's area = 7 X (5+6+5) = 112 units²

The area of the triangles = 2(base*hight/2) = base *height =6 X 4 =24 units²

Surface area = 112 +24 = 136 units ²

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
