​ Which is larger  8⋅3³  or  5⁴ and why?

• 8⋅3³ because it

  equals 264

• 8⋅3³ because it

  equals 216

• 5⁴ because it

  equals 2000

• 5⁴ because it

  equals 625

Polyhedron P is a cube with a corner removed and relocated to the top of P

• Their Surface Areas are the same.

• Q's Surface Area is Greater than P's Surface Area.

• P's Surface Area is Less than Q's Surface Area.

• Q's Surface Area is Less than P's Surface Area.

The formula for finding Area of a Triangle is:

A = b ⋅ h ÷ 2

 

****Why do you divide by 2?

• You should never divide by 2.  You just find b ⋅ h and you have the area of a triangle.

• You divide by 2 because a triangle is twice as big as a rectangle or parallelogram.

• You divide by 2 because a triangle is 1/2 the size of a rectangle or parallelogram.

• There isn't enough information to answer this question.
