Find the volume of the triangular prism.
1.)90 m3
2.)9 m3
3.)5 m3
4.) 45 m3​

You would start by writing the formula for a triangular prism. Which is V=1/2 x (a)x(c)x(h). Then while you add the number you multiply throughly. It’s easier is you just do 1/2=0.5

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
