# LEGOJeep Math and Science questions for fun

FunI created this Pop Quiz for kids to interact with the LEGOJeep for the YURI’s Night at NASA Ames a few years ago -Try it out – answers are at the bottom

B. Green

C. Grey

D. Black

**2. Which is the most difficult upper case letter to spell with LEGO bricks?**

A. The letter X

B. The letter K

C. the letter F

D. The letter T

*Grades 7-8 Science and Logic:*

**Why don’t 1 layer bricks fall off the plates when the LEGOJeep is driven?**

Test your answer by removing or adding a brick without glue.

3. A. Gravity B. Glue C. Friction and surface tension D. Protons

**4. Which area is the most prone to wind shear?**

A. Roof

B. Hood

C. Drivers door

D. Rear door

**5. How many vertices are in the letter X?**

Grades high school: Math surface area calculation:

**6. Calculate what is the total number of LEGO bricks of the 4 nub linear form to cover all the exposed plates.** The exposed

surface area total surface area is 99.305 square feet. A plate is 10 inches wide. It is

perfectly square. A plate has 32×32 nubs. To cover the jeep you will need 143 plates, 10

inches by 10 inches, the surface area of a 1×1 brick ( or one nub) is 5/16″ square. You

can not use red bricks to calculate the answer.

A. 36,608

B. 144,045

C 25,956

D. 13,076

**ANSWERS**

1. Answer A. Grey, 182 grey plate segments ( not including roof), 5 blues , 133 green plate

segments ( not including roof). There are no black plates.

2 Answer the letter X. Diagonals are the most difficult ( time consuming) to create since you need all single bricks to make a diagonal line

3 Answer C: Friction and surface tension, glue is not used to attach the bricks as known if

the person tested as directed.

4. Answer A: Roof

5 Answer D 4 vertices. The lines intersecting define only 4 angles

6. Answer: A 36,608, 256 4 nub bricks per plate, 256*143= 36,608
