Which expression represents the volume of the prism in terms of w, the width of the base? 5w2 cubic units 6w2 cubic units 5w3 cu
Nostrana [21]

The expression that represents the volume of the rectangular prism, in terms of the width w, is given as follows:

6w³ cubic units.

<h3>How to obtain the volume of a rectangular prism?</h3>

A rectangular prism is composed by three dimensions, given as follows:

  • Length l.
  • Width w.
  • Height h.

The volume of the rectangular prism is given by the multiplication of these three dimensions, as follows:

V = lwh.

From the image given at the end of the answer, the dimensions of the prism are given as follows:

  • Width w.
  • Length l = 2w.
  • Height h = 3w.

Hence the expression that gives the volume of the rectangular prism is given as follows:

V = w x 2w x 3w = 6w³ cubic units.

<h3>Missing Information</h3>

The prism is given by the image shown at the end of the answer.

A gift box has a volume of 450 cubic inches. The width of the box is 4 inches less than the length. The height is twice the widt
VashaNatasha [74]

Answer:

width = 5 in

length = 5+4=9 in

height = 2(5)= 10 in

Step-by-step explanation:

A gift box has a volume of 450 cubic inches.

Let 'w' be the width of the box

The width of the box is 4 inches less than the length.

length = w+4

The height is twice the width.

height = 2 \cdot width

height = 2w

Volume of box = length times width times height

V=(w+4)(w)(2w)

450=(w+4)(w)(2w)

450=2w^3+8w^2

2w^3+8w^2-450=0

\quad 2\left(w-5\right)\left(w^2+9w+45\right)=0

w-5=0

w=5

\quad\left(w^2+9w+45\right)=0, this gives two complex values

so width = 5

length = 5+4=9

height = 2(5)= 10
