Answer:
320
Explanation:
The formula for the volume of a pyramid is V= (b x h)/3
v is the volume
b is the base you get it by multiplying the bases length and width in this case it would be 80 in( since 8 x 10 is 80)
h is the height in this case it would be 12 in
V= (b x h)/3
V= (80 x 12)/3
V= (960)/3
V= 320 in
