Asolid oblique pyramid has a square base with an edge length of 2 cm. angle bac measures 45°. what is the volume of the pyramid? 2.4 cm3 3.6 cm3 4.8 cm3 7.2 cm3

the answer my friend is c

step-by-step explanation:

step-by-step explanation:

the base of the pyramid has a square base with an edge length of 2 cm, thus a right triangle is formed by half of the length of the base, the height of the pyramid and the slant height.

therefore, using the trigonometry, we have

⇒

⇒

now volume of the pyramid is given by:

v= where ab is the area of the base and h is the height.

v=

v=

since, the answer is close to , therefore option b is correct.
