What is the surface area of a rectangular prism that has a height of 5 cm, a width of 10 cm, and a depth of 4 cm?

Ket [755]

Option C: $220 \ cm^2$ is the surface area of the rectangular prism

Explanation:

The height of the rectangular prism is 5 cm

The width of the rectangular prism is 10 cm

The depth of the rectangular prism is 4 cm

We need to determine the surface area of the rectangular prism.

The surface area of the rectangular prism can be determined using the formula,

$A=2(w l+h l+h w)$

Substituting $w=10$ , $h=5$ and $l=4$ in the formula, we get,

$A=2 \cdot(10 \cdot 4+5 \cdot 4+5 \cdot 10)$

Multiplying the terms within the bracket, we have,

$A=2 \cdot(40 +20+5 0)$

Adding all the values within the bracket, we get,

$A=2 \cdot(110)$

Multiplying, we have,

$A=220$

Thus, the surface area of the rectangular prism is $220 \ cm^2$

Hence, Option C is the correct answer.

Your Roasted Snout dinner cost you $45.99. You will tip your server 15% of the bill. What is the TOTAL cost of your bill (includ

irina [24]

Answer:

Step-by-step explanation:

The basic cost of the Snout is 45.99

15% of that amount = 45.99*15/100 = <u> 6.90</u>

Total Cost 52.89

You could figure out the total cost a slightly different way.

You could set up

Cost = snout (1 + 15%)

Cost = snout(1 + 15/100)

Cost = snout( 1 + 0.15)

Cost = 45.99(1.15)

Cost = 52.89

Helpppp!! i’m willing to give all my points and brainliest, especially w explanation!

Rainbow [258]

Here are the basic rules for a right triangle:
One angle is always 90° or right angle.

The side opposite angle 90° is the hypotenuse.

The hypotenuse is always the longest side.

The sum of the other two interior angles is equal to 90°.

The other two sides adjacent to the right angle are called base and perpendicular.

a quick way to find angle 1, is just to look at the figure. there seems to be bisecting angles, so angle FCE and angle 1 are congruent. (meaning angle 1 is also 34 degrees)

hope this helps! lmk.
