70 m cubed
12,000 m3
12,000 m cubed
8,000 m3
8,000 m cubed
24,000 m3
24,000 m cubed
The correct answer is 8,000 m3 (8,000 cubic meters).
Volume of a rectangular pyramid = (1/3) x base area x height
Volume = (1/3) x (15 m x 20 m) x 80 m
Volume = (1/3) x 300 m2 x 80 m
Volume = (1/3) x 24,000 m3
Volume = 8,000 m3
