A rectangular solid has sides of 6 cm, 8 cm, and 10 cm.
Lubov Fominskaja [6]
To calculate the value of the surface of a rectangular solid, we add up all of the areas of the faces of the solid. For a rectangular solid, we calculate as follows:

SA = 2lw + 2wh + 2lh
SA = 2x6x8 + 2x8x10 + 2x6x10
SA = 96 + 160 + 120 
SA = 376 cm^3

Therefore, the correct answer is the second option. Hope this answers the question. Have a nice day.

Milton makes a trail mix for his hiking group. He mixes 1 1/4 pound of peanuts, 14 ounces of raisins, 12 ounces of walnuts, and
Veronika [31]

Answer:

7 ounces of trail mix each hiker receive.

Step-by-step explanation:

Given:

Milton makes a trail mix for his hiking group. He mixes 1 1/4 pound of peanuts, 14 ounces of raisins, 12 ounces of walnuts, and 10 ounces of chocolate chips.

If Milton divides the trail mix equally among the 8 hikers in the group.

Now, to find the ounces of trail mix each hiker receive.

Pound of peanuts = 1\frac{1}{4}.

Now, using conversion factor convert pound into ounces:

1 pounds = 16 ounces.

\frac{5}{4}  pounds = \frac{5}{4} \times 16 = 20\ ounces.

Ounces of peanuts = 20.

Ounces of raisins = 14.

Ounces of walnuts = 12.

Ounces of chocolate chips = 10.

Now, we add all the ounces of peanuts, raisins, walnuts and chocolate chips to get the trail mix:

20+14+12+10\\\\=56\ ounces.

<u><em>Total ounces of trail mix = 56.</em></u>

<u><em>Total number of hikers = 8.</em></u>

As given, Milton divides the trail mix equally among the 8 hikers.

So, to get the trail mix each hiker receive we divide total number of hikers by total ounces of trail mix:

56\div 8

=7\ ounces.

Therefore, 7 ounces of trail mix each hiker receive.
