Answer:
(A)The height of each pyramid is One-half h units.
Step-by-step explanation:
Height of the Cube = h units
Volume of the Cube 
If Base of the cube =Base of the square pyramid
Base of the square pyramid = h units
Since Volume of the Cube = Volume of Six Square Pyramids
Then:
Let us say that:
x = the number of T shirts bought = 4
y = the number of leather jackets bought = 1
a = the price of the T shirts
b = the price of the leather jackets
With the given variables, we can say that the total cost
is:
total cost = a x + b y
Since, b = 6 a, therefore:
total cost = a x + 6 a y
total cost = a (x + 6 y)
Since total cost is 209, therefore we can calculate for a
since x and y are also given:
209 = a (4 + 6 * 1)
209 = a (10)
a = $20.9
<span>Therefore each T shirt cost $20.9</span>
