Answer:

2400

Step-by-step explanation:

$SA = 2(lw + lh + wh) = 2(20^2 + 20^2 + 20^2) = 2(3 * 20^2) = 2(3 * 400) = 2 * 1200 = 2400$

Surface Area=2400

Step-by-step explanation:

To find the surface area we need to use this formula: Surface Area=6a^2

Where a is the side lengths that are being provided by the cube, now we plug in 20 as a into the formula.

Surface Area=6(20)^2

Surface Area=6(400)

Surface Area=2,400

Hope I helped, have a nice day :)

Find the distance between the two points rounding to the nearest tenth (if necessary)

Andrews [41]

Answer:

The answer is

<h2>2.8 units </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-3,3) and (-1,5)

The distance is

$d = \sqrt{( { - 3 + 1})^{2} + ({3 - 5})^{2} } \\ = \sqrt{ ({ - 2})^{2} + ( { - 2})^{2} } \\ = \sqrt{4 + 4} \\ = \sqrt{8} \: \: \: \: \: \: \: \: \\ = 2 \sqrt{2} \: \: \: \: \: \: \\ = 2.82842$

We have the final answer as

<h3>2.8 units to the nearest tenth</h3>

Hope this helps you
