You are asked to assist with a grade four class who will be selling small boxes of wildflower seed mix for Mother's Day. You are given a stack of construction paper cm wide and 20 cm long. You must instruct the class to cut identical squares from each corner , then fold the sides to create a lidless box in which the seeds can be placed . If the area of the base of the box must be 104 cm ^ 2 determine the length of each side of the corner squares . Draw and label a diagram . Clearly show your work and give your final answer to one decimal place.
You don't give the width of the paper, but if it s w cm, then you need
2((w-2x)(20-2x) + 2x((w-2x) + (20-2x))) = 104
So provide w and then solve for x
