Triangular Prisms Investigation Nets & Surface Area
2
Sketch a Triangular Prism First…draw the front face. Then some parallel lines... Then connect... Ta Da! Now draw the net… Is this net the only possible answer?
3
Which ones could be the net for this object? Must have: 2 congruent equilateral triangles 3 congruent rectangles Triangles not equilateral… Rectangles not congruent Triangles are equilateral… Need 3 congruent rectangles…
4
Draw the net and find the surface area 2 congruent scalene triangles 6 cm 2 1 rectangle 5cm by 7cm Find the area of each face. The sum is the surface area 6 cm 2 35 cm 2 28 cm 2 21 cm 2 Surface Area is 96 cm 2 1 rectangle 4cm by 7cm 1 rectangle 3cm by 7cm
5
Draw the net and find the surface area 2 congruent equilateral triangles 3 congruent rectangles 2 cm 8 cm 2 4cm 1.6 cm 2
6
Find the surface area
