B.17,052ft^3
C.5,600ft^3
D.11,774ft^3

Answer 1

First off, identify the formula, \[V = (\text{base})^2 \left(\frac{h}{3}\right)\] Our problem is in finding the height, this will take a few steps.

Answer 2

v=42^2(?/3)

Answer 3

v=1764(?/3)

Answer 4

Yes :) So far.

Answer 5

We know that the hypotenuse of the triangle is perpendicular to the base, therefore we can assume if splits that side of the square base in half.\[\frac{42}{2} = ~?\]

Answer 6

21

Answer 7

Alright, that means. Do you understand so far?

Answer 8

yes

Answer 9

We also know the triangle is a right triangle on the inside.
