Let b represent the length of the base and h represent the height. Because the length and width equal 30 2 h a height of 5 inches gives a length and width of 30 2 5 or 20 inches. This is achieved by the box of height 10 cm and base 20 cm by 20 cm.
Youve got your answer.
Substitute h in terms of s into the formula for volume. 1 2 0 0 b 2 4 h b. V s s 10800 - s²4 Expand. Compute the volume of the box.
