Cube side lengths are all the same. I'm guessing y is one of the sides. To get the surface area you do length X width X 6 (since there are 6 sides).firstly we need to divide 96 by 6. That is 16. Then we divide it by 2 because the length and width are the same. This is 8. The length of one side must be 8m.

The formula for finding the surface area of a cube is A=6y^2 where y is the side length. we know a=96. so we just isolate y.
96/6= 6y^2 / 6
16=y^2
sqrt (16) = sqrt(y^2)
4=y

So y is 4

Which number could be added to
Arturiano [62]

The number which could be added to both sides of the equation to complete the square is; -2.25.

<h3>Which number could be added to both sides of this quadratic equation to complete the square?</h3>

The quadratic equations give in the task content is; 1=x²-3x. Hence, to express the equation by completing the square method; we have;

1 - 2.25 = (x -3/2)² - 2.25

Hence, the number which should be added to both sides of the equation is; -2.25.

A rectangular prism has a length of 5 meters, a width of 6 3/4 meters, and a height of 3 1/2 meters. What is the volume of the p
kirza4 [7]

Answer:

<h2>118.13 m³</h2>

Step-by-step explanation:

Given,

Length ( l ) = 5 meters

Width ( w ) = 6 \frac{3}{4} meters

Height ( h ) = 3  \frac{1}{2} meters

Now, Let's find the volume of rectangular prism :

volume \:  = l \:  \times  \: w \:  \times  \: h

plug the values

= 5 \times  \frac{27}{4}  \times  \frac{7}{2}

Calculate the product

= \frac{5 \times 27 \times 7}{4 \times 2}

=  \frac{945}{8}

= 118.13 \:  {m}^{2}

Hope this helps..

Best regards!!
