Answer:


\mathbf{surface \ area} = \mathbf {64.5 cm^2}

Step-by-step explanation:

The missing diagram is attached in the file below:

The formula for calculating the surface of triangular prism is expressed as:


\mathbf{surface \ area} = \mathbf {bh + (s_1 + s_2 + s_3)H}

where ;

base b = 28 mm = 2.8 cm

height h of the triangle = 3.75 cm

the sides of the triangle
s_ 1, s_2 . s_3 = 2.8 , 4 and 4 respectively

the height if the prism H = 5 cm


\mathbf{surface \ area} = \mathbf {(2.8*3.75)+ (0.28 + 4+ 4)5}


\mathbf{surface \ area} = \mathbf {(10.5)+ (8.28)5}


\mathbf{surface \ area} = \mathbf {(10.5)+ (54)}


\mathbf{surface \ area} = \mathbf {64.5 cm^2}
