The area of a cross section perpendicular to the base of a rectangular prism is 45 square inches. If the length and width of the base are 5 inches each, what is the height of the prism
This is the concept of geometry, for us to get the height of the prism we proceed as follows; The lateral area=45 in^2 Lateral area=4*[length*width] length=x in width=5 in thus: 45=4[5*x] 45=20x x=45/20 x=2.25 inches long
