The correct answer would be Choice A.

The find the volume of the box, you need to multiply the L by W by H. Both the length and width have been reduced by 2 x's. And the height will be just x.

Therefore, LWH becomes (40 - 2x)(32 - 2x)x

Answer:

(a) (40−2x)(32−2x)x

Step-by-step explanation:

A box without a top is made from a rectangular piece of cardboard, with dimensions 40 inches by 32 inches, by cutting out square corners with side length x inches. both sides are cut by x inches

Length of the box = 40 -x-x= 40-2x inches

Width of the box = 32-x-x= 32-2x inches

height of the box is the side length = x inches

Volume of the box = length * width * height

= (40-2x)(32-2x)x

ExtremeBDS [4]

Given:

The expression is:

2b^3+5

To find:

The value of the given expression when b=3.

Solution:

We have,

2b^3+5

Substituting b=3 in the above expression, we get

2b^3+5=2(3)^3+5

2b^3+5=2(27)+5

2b^3+5=54+5

2b^3+5=59

Therefore, the value of given expression at b=3 is 59.
