Question

What is the volume of a square pyramid with base edges of 20 meters and a height of 30 meters?
a.600 m3
b.12,000 m3
c.4,000 m3
d.1,800 m3

Answer 1

h = 30
b = 20
\[\LARGE v = \frac{1}{3}b^{2}h\]

Answer 2

Am i suppose to multiply the base x height ?

Answer 3

First you need to square the base edge.

Squaring the base edge gets you the area of the base, so you could rewrite the equation like so:
\[v=\frac{1}{3}(\text {base area})(height)\]

Answer 4

i think its B when i solved it.

Answer 5

:) ! Thanks

Answer 6

Not quite. Need to multiply by (1/3)

Answer 7

ooooh :(
