Answer:
Volume of pyramid with square base is 1057.54 m³
Step-by-step explanation:
We are given:
Length of base of pyramid = 14.4 m
Height of pyramid = 15.3 m
We need to find:
Volume of pyramid with square base
The formula used is: 
Where a = base of pyramid and h is height
Putting values and finding volume

So, Volume of pyramid with square base is 1057.54 m³
If your teacher wants you to factor, then use the difference of squares rule
9x^2 - 4
(3x)^2 - 2^2
(3x-2)(3x+2)
8z +3 - 2z < 51
6z + 3 < 51
-3. -3
6z < 48

6. 6
z<8
