Question

Find the volume of a square pyramid with base edges of 48 cm and a slant height of 26 cm. 11,520 cm^3
23,040 cm^3
7,680 cm^3
768 cm^3

Answer 1

is the 11,520 in the question?

Answer 2

@vivianrush

Answer 3

its one of the choices

Answer 4

okay

Answer 5

I think 7,680 but I'm not sure

Answer 6

By the Pythagoras theorem,
h^2 + 24^2 = 26^2
h^2 = 676 - 576 = 100
h = 10
The volume of a square pyramid is
V = (1/3)Ah
where A = area of the base and h = height.
V = (1/3)(48 cm)^2(10 cm)
V = 7,680 cm^3
