The bottom shape is a square prism with base edges of 4 inches and a height of 12 inches. What is the volume of this composite figure if the top shape is a right pyramid with a height of 3 inches? Answer 16 in3 144 in3 192 in3 208 in3
Find the volume of the prism, then the volume of the pyramid. Add them together. Done.
how would i find volume for bottem shape
add the 2 volumes Prism: V = base area x height Pyramid V = 1/3 base area x height the pyramid base area is the same as the prisms.
what am i supposed to get
i keep on getting numbers tthat arent even answers
4*4*12 = 192 This is the volume of the bottom rectangular prism. Pyramid volume is, if my memory serves correctly, Base^2 * height * 1/3 so the pyramid would be 4^2* 3* 1/3 = 16 So the total would be 208
