b. 144 in3
c. 432 in3
d. 1296 in3

Volume of box is

Step-by-step explanation:

Let x be the side of square corner

Length of box after cutting corners =22-2x

Breadth of box after cutting corners =15-2x

Height =x

Volume of box = (22-2x)(15-2x)x

Volume of box =

Differentiate w.r.t x

Substitute derivative =0

at

hence maximum

at  

hence minimum

So,Volume of box =

Hence Volume of box is
