It is given that
A pyramid 
has a 4 m by 4 m square top
Height = 12 m
Base = 20 m
The volume of a square pyramid with a is given by
V = (1/2) * ( Area of base + Area of ) * height of the from the base
V = 0.5 * ( 20 *20 + 4*4 ) * 12
V = 2496 cu.m
The volume of the pyramid is 2496 cu.m.

Answer:
$260
Step-by-step explanation:
Actual price + 8% of actual price=$280.80
Let x= actual price
8% of actual price=8/100 of x
=0.08x
x + 0.08x=$280.80
1.08x=$280.80
x=$280.80/1.08
x=$260
Price of the jacket before sales tax=$260
Check:
8% sales tax of $260
=8% of $260
=8/100×$260
=0.08×$260
=$20.8
Purchasing price= actual price+ sales tax
=$260+$20.8
=$280.80
