Answer:

<u>678.4 cm^2</u>

Step-by-step explanation:

total surface area of prism is equal to ph+2B where <em>p</em> represents the perimeter of the base, <em>h</em> the height of the prism and <em>B</em> the area of the base.

Firstly, we calculate the <u>perimeter of the base. </u><u>This is equal to 10 + 14 + 10 + 14, or 48.</u>

Secondly, we must calculate the <u>height of the prism, </u><u>which is shown as 8.3.</u>

Lastly, we must calculate the <u>area of the base, </u><u>which is 10 * 14, or 140.</u>

We can now substitute these values into the formula, ph + 2B to find the total surface area of the prism:

ph + 2B,

(48)(8.3) + 2(140),

398.4 + 280,

678.4

<em><u>This means that the total surface area of this prism is 678.4 cm^2</u></em>

A workers regular hourly rate of pay is $13. What is the workers total pay for working 40 regulars and 3 hours overtime at a rat
ANTONII [103]

Answer:

578.50

Step-by-step explanation:

The worker worked 40 hours at 13 dollars

40 * 13 =520

Then they worked 3 hours at 13(1.5) or 19.50

3*19.50 =58.5

The total amount of money earned is regular time plus overtime

520 + 58.5 =578.50
