The value of a rectangle is 128 cubic yards. The base of the prism has an area of 8 square yards.
san4es73 [151]

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>

=  >  \frac{8h}{8}  =  \frac{128}{8}

  • <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>

How do you divide integers
Tom [10]

You multiply or divide integers just as you do whole numbers, except you must keep track of the signs. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer.

<span>
When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive.</span>

<span>Positive x positive = positive 
Negative x negative = positive</span>

<span>When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative.</span>

<span>Positive x negative = negative
Negative x positive = negative</span>

<span>When you divide two integers with the same sign, the result is always positive. Just divide the absolute values and make the answer positive.</span>

<span>Positive ÷ positive = positive
Negative ÷ negative = positive</span>

<span>When you divide two integers with different signs, the result is always negative. Just divide the absolute values and make the answer negative.</span>
