Alex has 343 cubes like the one shown. He
uses all of the cubes to fill a box shaped like
a rectangular prism. There are no gaps between
the cubes.

a. What are the possible dimensions of the
larger rectangular prism?

b. What is the volume, in cubic feet, of the
larger rectangular prism?

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

r and t.

both are 64 degrees.
