Six pyramids are shown inside of a cube. The height of the cube is h units. The lengths of the sides of the cube are b. The area of the base of the cube, B, is square units. The volume of the cube is cubic units. The height of each pyramid, h, is . Therefore, b = 2h. There are square pyramids with the same base and height that exactly fill the given cube. Therefore, the volume of one pyramid is or One-thirdBh.

hey i’m new i won’t be answering any questions now bye peeps see you next time

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

it’s supposed to be -4+45=41
