Hey there! :)
Answer:
V = 1260 cm³.
Explanation:
Volume of a pyramid:
V = 1/3 (bh)
The base is a triangle, so use the formula A = 1/2 (bh).
A = 1/2 (14 × 18)
A = 1/2(252)
A = 126 cm².
Plug this into the volume of a pyramid formula:
V = 1/3 (30 × 126)
V = 1/3 (3780)
V = 1260 cm³. This is the volume of the pyramid shown.
