Answer:
126.
Step-by-step explanation:
Each rectangle is a step. We'll start with the top one. This is simple: 6 times 3.

The farthest left is 5 times 3.

The crossed one is 6 times 5.

The one to the right of the crossed one is 3 times 5, again.

The farthest right is 6 times 5, again.

The bottom one is 6 times 3, again.

Now, we add.

H(t)=-16t²+160
0=-16t²+160
16t²=160
t²=10
t=√10 or 3.16 seconds
