A rectangular prism measures 3ft by 6ft by 5ft. If the dimensions of the box were all quadrupled. How would the surface area of

Blababa [14]

The surface area of a shape is the amount of space on the shape

When the dimensions are quadrupled, the new surface area would be 16 times the initial surface area

<h3>How to determine the surface area</h3>

The surface area of a rectangular prism is:

$S = 2 * (lw + lh + wh)$

When quadrupled, we have:

$S_2 = 2 * (16lw + 16lh + 16wh)$

Factor out 16

$S_2 =16 * 2 * (lw + lh + wh)$

Substitute $S = 2 * (lw + lh + wh)$

$S_2 =16 * 2 * S$

The above means that:

The new surface area would be 16 times the initial surface area

What is the equation for the following graph? a. y=-4 b. y=4 c. x=4 d. x=-4

Naddika [18.5K]

Answer:

x=4

Step-by-step explanation:

Consider the coordinate pair (4,y)

We observe that,

y can take any real values to lie on the graph of the equation.

As y really isn't a constant, we exclude it and take the equation as x=4
