Question

A box is 5inches high, (2x+3) inched wide, and (3x+5) inches long. In terms of x, what is the volume of the box(including units)?

Answer 1

Theme: Areas
Volume = Base area x high
Base area = wide x long
Base area = (2x+3).(3x+5) = 6x²+19x +15
Volume = (6x²+19x+15).5
Volume = 30x² + 95x + 75
I hope have helped :)
