From a thin piece of cardboard 40 in by 40 in, square corners are cut out so that the sides can be folded up to make a box. what
lutik1710 [3]
The dimensions of the square base after cutting the corners will be (40-2x). The depth of the box will be x, so its volume is given by
  V = x(40-2x)²

You can differentiate this to get
  V' = 12x² -320x -1600
Setting this to zero and factoring gives
  (3x-20)(x-20) = 0
The appropriate choice of solutions is
  x = 20/3 = 6 2/3

The dimensions of the box of maximum volume are
  26 2/3 in square by 6 2/3 in deep

The maximum volume is
  (80/3 in)²(20/3 in) = 4740 20/27 in³

The diagram shows the width and height of a table. Mr. Howell wants to build a table with the same ratio of width and height as
just olya [345]

Based on the diagram and the ratio of width and height in it, the width that Mr. Howell should make his table is 48 inches .

<h3>How wide should Mr. Howell's table be?</h3>

The width of the table in the diagram is 12 cm and the height is 6cm.

This means that the ratio of width to height is:

12 : 6

2 : 1

As Mr. Howell wants his table to be 24 inches high, the width of the table would be:

2 : 1

x  : 24

Cross-multiply to get:

x = 48 inches
