Answer:
<h2><em><u>16</u></em><em><u> </u></em><em><u>yards</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>,</u></em>
Volume of the rectangular prism = 128 cubic yards
Base area of the prism = 8 square yards
<em><u>Let</u></em><em><u>,</u></em>
Height of the prism be = h
<em><u>As</u></em><em><u> </u></em><em><u>we</u></em><em><u> </u></em><em><u>know</u></em><em><u>,</u></em><em><u> </u></em>
Base area × height = Volume of the given prism
<em><u>Therefore</u></em><em><u>,</u></em><em><u> </u></em>
By the problem,
=> 8 sq. yd × h = 128 cu. yd
=> 8h = 128
- <em>(</em><em>On</em><em> </em><em>dividing</em><em> </em><em>8</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

- <em>(</em><em>On</em><em> </em><em>Simplification</em><em>)</em>
=> h = 16
<em><u>Hence</u></em><em><u>,</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>height</u></em><em><u> </u></em><em><u>(</u></em><em><u>h</u></em><em><u>)</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>prism</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>16</u></em><em><u> </u></em><em><u>yards</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
Answer:
Volume of rectangular prism in scientific notation is
cubic centimeters and in standard form
.
Step-by-step explanation:
Since we know that volume of a rectangular prism is length*breadth*height.
Sides of our rectangular prism are given in scientific notation as 
and
.
Let us substitute our values in volume formula,

Upon using exponent product property we will get,

Now let us convert our volume in standard form as,
Therefore, volume of rectangular prism in scientific notation is
cubic centimeters and in standard form
.
Answer:
about 12 people
Step-by-step explanation:
cir.=2πr=62.8 , so r=31.4/π , vol of tower= base area × hight = πr² × 11.5 ≈ 3609.17 cm³ , number of people= vol/300 ≈ 12
