Da Qin: The First Emperor wanted to train me to be the empress

"Only in this way can we roughly calculate the intensity of damage caused to the ground by meteorites falling from the sky."

The boy explained as he walked towards the ladder they had prepared, "As you can see, we have prepared five ladders of different heights."

"They are of five levels: two meters, five meters, eight meters, 11 meters and 14 meters in height."

Xuman and his daughter also saw that the five ladders were placed quite far apart.

It seems that these students did not want any influence on each other, so they made this arrangement.

In response, she smiled with even more satisfaction.

"First of all, we asked Lu Congjun to climb the lowest two-meter-high ladder."

Following the boy's words, the naive boy came out and climbed up the ladder quickly.

Immediately, everyone saw several boys using the lever principle to send the prepared stones up. Lu Congjun stood on the ladder with both legs and carefully picked up the stones.

The audience was stunned when they saw this, and some people couldn't help but stand up from their seats, staring at his movements.

The students who brought the stones quickly retreated, while Lu Congjun stood upright on the ladder, his hands naturally released, and the big stone fell to the ground with a whoosh.

Then there was a bang.

The audience swallowed their saliva instinctively, wondering what the students would do next.

But they soon found out.

The boy who only listened to the explanation spoke again: "Everyone saw it. Now that the stone has fallen to the ground, it is obvious that a hole has been made in the ground."

Everyone: "..." How can we not break out of the hole? Such a big stone fell from such a height.

Although he thought so in his heart, no one said anything.

Because everyone saw that the remaining five students, three men and two women, came forward with tools and first drew a line close to the ground where the stone fell.

At the same time, the narrator is still explaining: "Now, my classmates will use chalk to draw the location where the stone fell into the pit."

"If you move the stone out again, you can calculate how deep the pit is." "The remaining places will be measured using the same method. Please wait a moment."

"It's so noisy."

Behind Ying Zheng and his daughter, the Minister of Civil and Military Affairs and the deans of each college began to discuss in low voices, "It seems that these students have really learned something."

"That's natural."

When the two giants of the Mohist family and the Gongshu family heard someone praising their students, they answered proudly.

Then the two looked at each other, then turned away with a silent hum.

The civil and military officials did not pay any attention to the reaction between the two of them, and each murmured, "It's only two meters... By the way, how many feet is two meters?"

"Her Royal Highness said that one meter is approximately equal to my Qin's 1.442 feet, and 2 meters is 2.884 feet."

"Oh, Your Majesty, it's so useful to teach you the decimal point."

"It's easy to use, but it's a bit troublesome to calculate."

"What's the trouble? It's just rounding up anyway, hahaha..."

"No, the ladder is two meters tall, plus the height of the student holding the stone, it's more than two meters."

"It's not much different. Then the student isn't standing at the highest position?"

"You are just an amateur, right? The height of the ladder that people talk about is the highest position a person can stand on, not the height to the top."

"Including the student's height, it's three meters tall. Wow, eight feet tall!"

……

Xu Man listened to the discussion of the civil and military ministers behind him, and a smile appeared on his lips.

It's really not in vain that she has comprehensively popularized these basic knowledge in the past few years. Look, these ministers know how to convert the unit of Qin feet to meters.
