The volume of a pyramid is given by:
Where:
• Ab is the area of the base,
,
• h is the height.
In this case, we have:
• a = 3 units,
,
• b = 7 units,
,
• c = 9 units,
,
• Ab = b * c,
,
• h = a = 3 units.
Replacing the data in the formula above, we get:
Answer: 63 units³

<u><em>Answer:</em></u>45 ft</span>²<span> will be blue
<u><em>Explanation:</em></u><u>1- getting the area of the wall:</u>
area of the rectangle can be calculated as follows:
area = length * width
we are given that:
length = </span>
ft<span>
width = </span>
<span> ft
Now, substituting in the above rule, we can get the area as follows:
area = </span>
*
= 135 ft²<span>
<u>2- getting the area that would be pained blue:</u>
We are given that </span>
<span> of the area of the room would be painted blue, this means that:
area of blue = </span>
<span> * area of room
area of blue = </span>
<span> * 135
area of room = 45 ft</span>²<span>
Hope this helps :)</span>
