What is the volume in cubic cm of a pyramid whose area of the base is 25 sq cm and height 9 cm ?
Answer & Solution
Correct Answer:
Option
B
Volume of pyramid :
$$\eqalign{ & = \frac{1}{3} \times {\text{Area of base}} \times {\text{Height}} \cr & = \left( {\frac{1}{3} \times 25 \times 9} \right){\text{c}}{{\text{m}}^3} \cr & = 75\,{\text{c}}{{\text{m}}^3} \cr} $$
$$\eqalign{ & = \frac{1}{3} \times {\text{Area of base}} \times {\text{Height}} \cr & = \left( {\frac{1}{3} \times 25 \times 9} \right){\text{c}}{{\text{m}}^3} \cr & = 75\,{\text{c}}{{\text{m}}^3} \cr} $$
