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
