Answer 1

Answer:

$V=210\ cm^3$

Step-by-step explanation:

The legs measuring 10 cm and 14 cm.

The height of the pyramid is 9 cm.

We need to find the volume of the pyramid. The formula for the volume of a right pyramid is given by :

$V=\dfrac{1}{3}Bh$

Where

B is area of base,

$B=\dfrac{1}{2}\times 10\times 14=70\ cm^2$

Put all the values,

$V=\dfrac{1}{3}\times 70\times 9\\\\V=210\ cm^3$

So, the volume of the right pyramid is equal to $210\ cm^3$.
