What is the volume of the square pyramid? Round to the nearest tenth.

goldfiish [28.3K]

Answer:

$V=718.7\ cm^{3}$

Step-by-step explanation:

we know that

The volume of the square pyramid is equal to

$V=\frac{1}{3}b^{2}h$

we have

$b=14\ cm$ ----> the length of the base of the square pyramid

$h=11\ cm$ ---> the height of the pyramid

substitute the values in the formula

$V=\frac{1}{3}(14)^{2}(11)$

$V=718.7\ cm^{3}$
