Pyramid a is a square pyramid with a base side length of 9 inches and a height of 10 inches. pyramid b has a volume of 1350 cubic inches. how many times bigger is the volume of pyramid b than pyramid a? give the answer as a percent. provide an explanation and proof for the answer.

In this problem, we just have to compute the volume of pyramid a in order to compare the sizes or volumes of the two pyramids. the volume of the pyramid is equal to 1/3* s^2* h where s is equal to the length of the square base. the volume of pyramid a is 270 cubic inches. the ratio then is equal to 1350/270 equal to 5. 

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
