Solution:
The volume of rectangular pyramid is given as:
[tex]volume = \frac{1}{3} \times l \times w \times h[/tex]
Where,
l is length and w is width and h is height
From given,
v = 448
l = 8
w = 12
Substituting the values we get,
[tex]448 = \frac{1}{3} \times 8 \times 12 \times h\\\\448 = 32h\\\\h = \frac{448}{32}\\\\h = 14[/tex]
Thus height of pyramid is 14 units
