Answer:

The answer is

<h2>376 cm²</h2>

Step-by-step explanation:

Since the rectangular box is a cuboid,

Total surface area of a cuboid is given by

<h3>2( lw + wh + lh)</h3>

Where

l is the length

w is the width

h is the height

From the question

l = 10 cm

w = 8cm

h = 6cm

Substitute the values into the above formula

That's

Total surface area of the rectangular box is

2 [ (10)(8) + (8)(6) + (10)(6) ]

2 [ 80 + 48 + 60 ]

2( 188)

We have the final answer as

<h3>Total surface area = 376 cm²</h3>

Hope this helps you

Flura [38]

Answer:

h ≤ 8

Step-by-step explanation:

Hans charges $7 per hour and pays $5 in equipment fees.

$5 is fixed in this case. Let the possible number of hours be h.

According to question,

Atleast means less than equal to. So,

7h-5≤51

Add 5 to both sides.

7h+5-5 ≤ 51+5

7h ≤ 56

h ≤ 8

So, the number of hours be less than equal to 8.

Find the sum of the constants a, h, and k such that
ra1l [238]

Answer:

  3

Step-by-step explanation:

The value of "a" is the coefficient of x^2, so we know that is 2.

__

<u>Solve for h</u>

Now, we have ...

  2x^2 -8x +7 = 2(x -h)^2 +k

Expanding the right side gives us ...

  = 2(x^2 -2hx +h^2) +k

  = 2x^2 -4hx +2h^2 +k

Comparing x-terms, we see ...

  -4hx = -8x

  h = (-8x)/(-4x) = 2

__

<u>Solve for k</u>

Now, we're left with ...

  2h^2 +k = 7 = 2(2^2) +k = 8 +k

Subtracting 8 we find k to be ...

  k = 7 -8 = -1

__

And the sum of constants a, h, and k is ...

  a +h +k = 2 +2 -1 = 3

The sum of the constants is 3.
