The volume of a prism is given by its base area multiplied by its height.
The bases are two right triangles. If we project everything on the xy plane, we can see that the vertices of the base triangle is
So, leg AB is 3 units long, and leg AC is 4 units long. This means that the area of the triangle is
The height of the prism connects, for example, points and , so it's 5 units long. So, the volume of the prism is
Answer:
9cm
Step-by-step explanation:
3/12 is equal to 1/4 ratio between the size of the window and the building.
Apply that ratio to the the 36 centimeters to get 36/4 which is equal to 9 centimeters.
R equals 20 in this situation.
