Question

PLEASE HELP!!

A box without a top is made from a rectangular piece of cardboard, with dimensions 4 m by 2 m, by cutting out square corners with side length x.

Which equation can be used to determine the greatest possible volume of the cardboard box?

A. (4−x)(2−x)x=0

B. (4−2x)(2−2x)x=0

C. (x−4)(x−2)x=0

D. (4x−2)(2x−4)=0

Answer 1

After each is being cut by x , then :

New length = 4-x
New width = 2-x
Height = x

Volume = (L) . (W) .(H) ===> (4-x)(2-x)(x)=0:
