Question

lid right pyramid has a square base. The base edge length is 2 cm longer than the height of the pyramid. If the height is 6 cm, what is the volume of the pyramid? 24 cm3 48 cm3 128 cm3 144 cm3

Answer 1

Answer:

128 cm3

Step-by-step explanation:

we know that

The volume of the square base pyramid is equal to

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

where

b is the length side of the square base

h is the height of the pyramid

we have

$h=6\ cm$

$b=h+2$

substitute the value of h

$b=6+2=8\ cm$

Find the volume

$V=\frac{1}{3}(8)^2(6)=128\ cm^3$
