Last one! This one mentions that the base of this prism is 35 cm squared and then asks the volume as well. The possible answers for this one are: ~336 cm cubed ~210 cm cubed ~262 cm cubed ~280 cm cubed Please don't just give me the answer, I want to be able to understand how to do these so I'll be at least a little less frustrated with myself. xD Thank you for taking the time to read!
The volume of a prism is the area of the base times the height. First, figure out which sides are the bases. Find the area of one base. Then find the height, and mulltiply the area of the base you calculated above by the height.
The first prism has trapezoids as bases. Find the area of one of the trapezoid bases. Then multiply that area by the height of the prism to find the volume of the prism.
is it 12..? It's sort of confusing with the numbers everywhere I can't tell which one is assigned to what part of the prism. is 12 the area of one of the trapezoid bases?
The area of a trapezoid is the the sum of the bases over 2, times the height. |dw:1442516031814:dw|
