Arectangular piece of cardboard, whose area is 352 square centimeters, is made into an open box by cutting a 2-centimeter square from each corner and turning up the sides. if the box is to have a volume of 432 cubic centimeters, what size cardboard should you start with?

Dimension of cardboard is 22 m by 16 m

Explanation:

Given that,

Area = 352 cm²

Side of each square cutting from corner = 2 cm

Volume of box = 432 cm³

Let the two sides are x and y.

The area of the rectangular piece is

-------- (1)

The volume of the rectangular piece

x=16,22

Put the value of x in the equation (I)

For x = 16

For x = 22

Dimension of cardboard is 22 m by 16 m

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.
