Hii :)

First, what is volume?

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface. For example, the space that a substance (solid, liquid, gas, or plasma) or 3D shape occupies or contain

<u><em>FIRST ONE IS UNDERLINED</em></u>

<u>Now, lets answer.</u>

<u>Volume = lwh</u>

<u>Surface Area = 2(lw + lh + wh)</u>

<u />

<u />

<u>So, whats the answer?</u>

<u>Area of the floor is 693 sq ft</u>

<u />

<u />

<u />

<u>--------------Steps--------------</u>

<u />

<u />

<u>The formula for the area of a rectangle is:</u>

<u />

<u />

<u>A=l×w</u>

<u />

<u />

<u>The formula for the volume for a rectangular cube is:</u>

<u />

<u>V=l×w×h</u>

<u />

<u />

<u>We can substitute:</u>

<u />

<u>2079ft  3 for V</u>

<u />

<u />

<u>3ft for h</u>

<u />

<u />

<u>A for  l×w</u>

<u />

<u>And then solve for A  to find the area of the floor: v=l×w×h becomes:</u>

<u />

<u />

<u>2079ft 3=A×3ft</u>

<u />

<u>Therefore,Area of the floor is 693 sq ft</u>

The second question:

8 1/2 is 8.5. 3 1/4 is 3.25

3*8.5*3.25 = 82.875

About 4/10 of the population has blood type O+. What percent of the population has blood type O+?
fenix001 [56]

If 4/10 of the population have blood type O+, that means 40% of the population have that blood type. To change a fraction to percent, the easiest way is to make the denominator 100. To do this, multiply the whole fraction by 1 (1/1, 2/2, etc). In this case, multiply by 10/10. 4/10 * 10/10 is equal to 40/100. Then, if you have a denominator of 100, the numerator is the percent. Therefore, 40/100 is 40%.
