Volume of square pyramid can be calculated by the formula :
V=
a is the length of base and h is the height of the pyramid.
In the given figure a= x in.and h = 
in.
Volume of pyramid given V =486 cubic inches.
Substituting these values in volume of pyramid we have:
486= 
÷ 3
Or 486=
486= 
Multiplying both sides by 12
5832 =
Or x= 18 in.
What's all the answers so I can figure it out which answer it would be?
Answer:
= 486 in²
Step-by-step explanation:
Linear scale factor = Image distance/object distance
Therefore; Linear scale factor = OL'/OL
= 54/ 12
= 9/2
Area scale factor is equivalent to the square of linear scale factor
Thus;
Area scale factor = (9/2)²
= 81/4
Hence; 81/4 = Area of larger rectangle/Area of smaller rectangle
Area of the smaller rectangle = 4 ×6 = 24 in²
Therefore;
Area of enlarged or larger pic = 81/4× 24
<u>= 486 in²</u>
