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.
Answer: x=14
Step-by-step explanation:
Subtract 2
from both sides of the equation.
X=16−2
Subtract 2
from 16
.
X=14
