Answer:
The correct answer is option 3. volume of Pyramid=2520 cm³
Step-by-step explanation:
Formula:
Volume of triangular pyramid is 1/3 *(Base area * Height)
Area of triangle = 1/2(Base * Height)
<u>To find Base area of base triangle</u>
Base b = 18 cm
Height = 24 cm
Area A = 1/2(Base * Height) = 1/2(18*24) = 216 cm²
<u>To find the volume of </u>pyramid
Base area = 216 cm² and height = 35 cm
Volume V = 1/3 *(Base area * Height)
V = 1/3(216*35) = 2520 cm³
Therefore option 3 is the correct answer
