The maximum possible volume of this type of box that can be made from a 20 cm by 20 cm square of paper is 512cm³.
<h3>How to calculate the volume?</h3>
From the information, when the side of 1cm are cut, this will become an open box. The volume will be:
= 18 × 18 × 1
= 324cm³
Also, when 2cm is cut, the volume will be:
= 16 × 16 × 2
= 512cm³

Since you are given two equations
y = 2x - 5
y = x^2 - 5
Substitute into one of the equations...,
;x^2 - 5 = 2x - 5
;x^2 - 2x = -5 + 5
; x^2 - 2x = 0
Hence you factorise the equation..,
; x(x - 2) = 0
Hence....x = 0 and 2
And for the value of y
; Substitute with the value of x onto one of either equations
for...x = 2
;y = 2(2) - 5....y = -1
for...x = 0
;y = 2(0) - 5....y = -5
The perimeter is all the sides added up.
s1+s2+s3+s4= p
So, 12+ 6+ 8+ 17= the perimeter.
12+6+8+17 = 43
The answer is 43.
I hope this helps!
