The net of an isosceles triangular prism is shown here. what is the surface area, in square units, of the triangular prism? a.94 units^2 b.98 units^2 c.129 units^2 d.136 units^2

First, area of the middle rectangle:  6*7=42 unit^2
Top rectangle = 5*7 = 35 units
bottom rectangle = 5*7 = 35 units
Area of each end (triangle) = base * height/2 = 6*4/2= 12
Total area of ends = 2 * 12 = 24

Surface of prism (= area of net)
= 42+35+35+12+12 
= 136 unit^2

Aand b are correctly balanced reactions. they have the same number of atoms in both sides of the reaction
