The museu Blau in Barcelona Spain is a natural science museum built in a shape of a triangular prism. The base of the building is an equilateral triangle 180 meters on each side. The height of the prism is 25 meters

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

where did you get them? if you picked from the grass, is is probably poisonous.
