Find the volume of a triangular prism with the following dimensions. round to the nearest cubic unit. triangle base: 5 ft triangle height: 3 ft prism height: 7.5 ft

Find the area of a triangle first

a=1/2bh(triangle)

a=1/2(15)

a=7.5

multiply that by the height of the prism

7.5*7.5

=56.25ft^3

you do the rounding

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

x=half
