1.<br> 6 cm<br> 6 cm<br> Find the surface area of the cube.<br> Surface Area = [?] cm²<br> 6 cm
Mariulka [41]

Answer:

The <em>surface area</em> of the cube is equal to 216 cm².

General Formulas and Concepts:
<u>Geometry</u>

Surface Area Formula [Cube]:
\displaystyle \text{SA} = 6a^2

  • <em>a</em> is a side length

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify given variables</em>.

<em>a</em> = 6 cm

<u>Step 2: Find Surface Area</u>

  1. [Surface Area Formula - Cube] Substitute in <em>a</em>:
    \displaystyle \text{SA} = 6(6 \ \text{cm})^2
  2. Evaluate:
    \displaystyle \text{SA} = \boxed{216 \ \text{cm}^2}

∴ we have found the surface area of the cube to be 216 cm².

After 10% tax, the phone cost $220. What was the original price?​
Burka [1]

Answer:

$198

Step-by-step explanation:

To find how much the tax was, we multiply 10% by 220. We do this in decimal form, so we write it as 0.1*220. 0.1*220 is 22. Although, we don't stop there. Now that we know how much tax is, we must subtract the tax from the price with tax to find the OG price. 220-22 is 198. That means our answer is $198. Hope this helps!
