A rectangular prism has a length of 8 in., a width of 4 in., and a height of 2 1/4 in.

marishachu [46]

The number of cubes needed to fill the rectangular prism 4608 cubes.

<h3>How to find volume of rectangular prism and cube?</h3>

volume of rectangular prism = lwh

where

l =length
w = width
h = height

Therefore,

volume of the rectangular prism = 8 × 4 × 9 / 4 = 72 inches³

volume of the cube = l³

where

l = length

Therefore,

volume = (1 / 4)³

volume of the cube = 1 / 64 inches³

Therefore,

The number of cubes needed to fill the rectangular prism = 72 ÷ 1 / 64

The number of cubes needed to fill the rectangular prism = 72 × 64 = 4608

Tomtit [17]

Answer:

Total tape used by marge is 6 inches .

Step-by-step explanation:

As given

marge cut 16 pieces of tape for mounting pictures on poster board.

$Each\ piece\ of\ tape\ was\ \frac{3}{8}\ inch\ long.$

Total tape marge uses = Number of pieces × Each piece length

$Total\ tape\ marge\ uses = \frac{16\times 3}{8}$

Total tape marge uses = 2 × 3

= 6 inches

Therefore the total tape used by marge is 6 inches .

Given the equation square root of quantity 3x plus 6 end quantity equals 3, solve for x and identify if it is an extraneous solu

Novay_Z [31]

Solution is not extraneous, x=1 is correct answer

Step-by-step explanation:

We need to solve the equation $\sqrt{3x+6}=3$ and find value of x.

Solving:

$\sqrt{3x+6}=3\\Taking\,\,square\,\,on\,\,both\,\,sides\\(\sqrt{3x+6})^2=(3)^2\\3x+6=9\\Simplifying:\\3x=9-6\\3x=3\\x=3/3\\x=1$

So. Value of x = 1

Now checking if solution is extraneous or not

Solution is extraneous if value of x doesn't satisfy the given equation.

Checking: putting x=1 in the equation $\sqrt{3x+6}=3$

$\sqrt{3x+6}=3\\\sqrt{3(1)+6}=3\\\sqrt{9}=3\\ 3=3$

Since x=1, verifies the given equation so, x=1 is not extraneous solution

Solution is not extraneous, x=1 is correct answer
