Question

need help pronto...................................................................................................The bottom shape is a square prism with base edges of 5 feet and a height of 15 feet. What is the volume of the composite figure if the top shape is a right pyramid with a height of 3 feet?

375 ft3

225 ft3

25 ft3

400 ft3

Answer 1

D

Answer 2

nah last time u told me d and it was wrong

Answer 3

ts the same the only difference is you change the numbers
V = bwh or V = Bh ---- the small b is the base while the big B is the area of the base.
so we plot the information V = (5)(5)(15) V = 375
So the volume of the rectangle prism is 375, now we have to find the right pyramid.
the formula for the right pyramid is V = 1/3Bh; so once again we plot our information.
B = (5)(5) = 25
V = 1/3(25)(3)
V = 1/3(75)
V = 25
Now we add the two volumes to find the volume for the entire figure;
V = 375 + 25
V = 400
Plus we add the ft sign since it is in feet, and the cube since it is volume;
the answer would be 400 ft^3
