A rectangular prism measures 4 ½ inches long, 6 ½ inches wide, and 2 ½ high. How many cubes with side length of ½ inch are needed to fill the prism?

it's a volume question

Explanation:

First, find the volume of the small shape.

Then, divide the volume of the bigger shape.

Finally, divide the big shape volume by the small shape volume.

=

5400

Smaller shapes will fit into bigger shapes.

Step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
