Aprism and two nets are shown below: part a: which is the correct net for the prism? explain your answer. (2 points) part b: write the measurements of sides ab, bc, and cd of the correct net. (4 points) part c: what is the surface area of the prism? show your work. (4 points) if possible explain.

First question, net A is correct because the triangles on either side line up with the hypotenuse of the prism and the back side.

Second question, AB= 3 inches
BC=5 inches CD= 8.6 inches.

Third question, The surface area of the prism is all of the sides’ areas added together. The base has an area of 8.6 *4 which equals 34.4. The area of a triangle is 1/2bh which is one half the base times the hight. In this case there are two triangles, so the new equation is multiplied by 2 to make bh or 3 *4 which equals 12. The next side to calculate is the back wall which is 5 times 3 or 15. Lastly, the hypotenuse (8.6*5) or 43. Add these together and you get 104.4 inches squared.

Coral reefs,temperate grasslands, and kelp forests are all in danger.
