Answer:
4,050 cubic feet
Step-by-step explanation:
Split into a cube and a pyramid, calculate volume of each, then add together for total volume.
Volume of a cube is V=lwh
Volume of a pyramid is V=
[tex] \frac{lwh}{3} [/tex]
so cube first...
15×15×15=3,375
now pyramid...
15×15×9=2,025
2,025/3=675
Now add both together for total volume...
3,375+675=4,050
