If a triangular pyramid has a base area of 10ft and a height of 6ft, what is the volume? . 20ft^3

. 40ft^3

.60ft^3

.80ft^3

.120ft^3

20 ft³

Step-by-step explanation:

volume of triangular pyramid =

Therefore, the volume is:

what does x eaqual

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
