Answer:
336.02 square centimeters
Step-by-step explanation:
The surface area is the area of all the surfaces of the prism shown.
The prism has 7 surfaces.
Top and Bottom are pentagons with side lengths of 5.
The other 5 side surfaces are rectangles with length 10 and width 5.
Note the formulas of area of pentagon and area of rectangle below:
Area of Rectangle = Length * Width
Area of Pentagon = , where a is the side length
Lets find area of each of the surfaces:
<u>Top Surface</u> (Pentagon with side length 5) =
<u>Bottom Surface</u> = same as Top Surface = 43.01
<u>Side Surface</u> (rectangle with length 10 and width 5) = 10 * 5 = 50
There are 5 side surfaces that are each 50 sq. cm. so area would be:
<u>Area of 5 Side Surface</u> = 5 * 50 = 250
Total Surface Area = 250 + 43.01 + 43.01 = 336.02 square centimeters
<h3><u>Question:</u></h3>
Winton was given $14 to spend at a school fair he spent 3/7 playing games how much money is left
<h3><u>Answer:</u></h3>Amount left with winton is $ 8
<h3><u>Solution:</u></h3>Given that Winton was given $14 to spend at a school fair
He spent playing games
To find: money left with Winton
From given information,
Money given to Winton = $ 14
Amount spent on games =
Thus we can say,
Amount spend on games = of total money he has
Thus he spend $ 6 on playing games
<em><u>Money left with Winton:</u></em>
Money left = total money he had - money spent on playing games
Money left = 14 - 6 = 8
Thus amount left with winton is $ 8
