Base of the Triangle=8 Units

Area of the Triangular Face

$=\frac{1}{2}bh\\ =\frac{1}{2}*8*6\\=24 $ square units$

<u>Rectangular Faces</u>

Area of Rectangular face with dimension 12 by 10=12 x 10=120 Square Units

Area of Rectangular face with dimension 12 by 8= 12 X 8=96 Square Units

Area of Rectangular face with dimension 12 X 6=12 x 6=72 Square Units
