Because there are more than 2 lengths for the sides and because the small triangle faces are right angles we will use this formula:

V=(1/2)bhl
which is equivalent to V=Al  (A=(1/2)bh and A is Area)

b=12in
h=35in
l=40in

A=(1/2)•12in•35in
A=(1/2)•420in
A=210in^2

V=Al
V=(210in^2)•40in
V=8400in^3

Making your answer D. 8400 inches cubed

Justify your reasoning
love history [14]

Answer:

Yes

Step-by-step explanation:

You can conclude that ΔGHI is congruent to ΔKJI, because you can see/interpret that there all the angles are congruent with one another, like with vertical angles (∠GIH and ∠KIJ) and alternate interior angles (∠H and ∠J, ∠G and ∠K).

We also know that we have two congruent sides, since it provides the information that line GK bisects line HJ, meaning that they have been split evenly (they have been split, with even/same lengths).

<u><em>So now we have three congruent angles, and two congruent sides. This is enough to prove that ΔGHI is congruent to ΔKJI,</em></u>
