A packaging box has a length that is 5 more than width. The height is 10 more than length. Express in algebraic form the volume of the packaging box.
w = width {length is 5 more than the width}w + 5 = length w + 15 = height {height is 10 more than the length}Volume of a box (rectangular prism) = length x width x heightV = lwh= w(w + 5)(w + 15) {multiplied width by length by height} = (w² + 5w)(w + 15) {used distributive property} = w³ + 15w² + 5w² + 75w {used FOIL method / distributive property} = w³ + 20w² + 75w {combined like terms}Ask the House
