1. Summarize the the given situation in your own words. (What do you notice?)
2. Explain: What is the essential information you can use to find the solution.

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

i would need to see the dot plot : )

answer:

your answer is: c. 196 7/8 in^3.
