There is a 28 cm long, 24 cm wide rectangular cardboard, it is made into a 6 cm high as possible as large as the cuboid carton, carton volume What's the volume of the carton

Cut the square with the side length of 6cm from the four corners of the rectangular cardboard,
The side length of the square is the height of the carton
Carton length = 28-6 * 2 = 16 cm
Width of carton = 24-6 * 2 = 12cm
Volume of carton made
=16*12*6
=1152 CC
=1.152 L

A rectangle is 24 cm long and 16 cm wide. It can be used to make several kinds of lidless cartons with different volumes

Take integer, design the following three
(1) The length, width and height are 10, 6 and 2 respectively, and the volume is 2 * 6 * 10 = 120
(2) The length, width and height are 9, 5 and 3 respectively, and the volume is 3 * 5 * 9 = 135
(3) The length, width and height are 8, 4 and 4 respectively, and the volume is 4 * 4 * 8 = 128
It can be seen that the second type has the largest volume

If two parallelograms have the same area, they must have the same perimeter
Is that right

No, two parallelograms of equal area do not necessarily have the same perimeter
