The volume of a cube is the length of its side cubed. In this case, the length is 3c^(6)d^(2). You must cube this to get the answer.

To do this, we first cube the coefficient of the first term, 3. 3 cubed is 27.

Next, we must cube c^(6) and d^(2). You raise an exponent to a power by multiplying the exponent by the power it is being raised to. In this case, we will multiply 6 and 2 by 3, and we get 18 and 6.

Our answer is:

27c^(18)d^(6)

Hope this helped and good luck!

A rectangular piece of plywood has a diagonal that measures three times the width. The length of the plywood is three feet more

Karolina [17]

Answer:

The length of diagonal is 4.922 feet.

Step-by-step explanation:

Let the width be = w

Let the diagonal be = d

Let the length be = l

Given is that the diagonal measures three times the width, this gives: $d=3w$

Also given is the length of the plywood is three feet more than the width. This is : $l=x+3$

Now, in terms of x we get:

Width = x

Length = (x+3)

Length of Diagonal = 3x

Now applying Pythagorean Theorem

$a^{2}+b^{2}=c^{2}$

$x^{2}+(x+3)^{2}=(3x)^{2}$

$x^{2}+x^{2}+6x+9=9x^{2}$

Solving this we get,

$-7x^{2}+6x+9=0$

We will use quadratic formula to solve this and get the answer,

x = 3/7 +/- (12√2) / -14

x = 1.64075 or x = -0.783612(neglect this negative value)

So, x = 1.64075 feet

Now length of diagonal is 3x = 3*1.64075 = 4.922 feet

So, length of diagonal is 4.922 feet.
