Geometry Review

Volume

1

What does B stand for?

B=area of the base

2

What is the formula for volume?

V=Bh

3

What is the volume of a rectangular prism with a rectangle base of 6 and 3 and a height of 8?

V=Bh

=(6)(3)(8)
=(18)(8)
V=144

4

What is the area of the base if the base has 5 and 7 and a prism height of 10

B=bh
=(5)(7)

B=35

5

What is the volume of the prism if the base is 9.75 and 3.5 and a prism height of 12?

V=Bh
=(9.75)(3.5)(12)
=(34.125)(12)

V=409.5

Parallelogram

1

What is the formula for a parallelogram and rectangle? 

A=bh

2

What is the area of the parallelogram if the base is 5, the height is 4, and the side length is 3?

A=bh
=(5)(4)

A=20

3

What is the area of the rectangle if the base is 2.25 and the height is 4?

A=bh
=(2.25)(4)

A=9

4

Find the difference between the rectangles if if rectangle 1 has a base of 5 and a height of 8, and rectangle 2 has a base of 7 and a height of 4.

rectangle 1 =40
rectangle 2=28

40-28=12

5

What is the height of the rectangle if the area is 144 and the base is 6?

A=bh
144=(6)h
h=24

Montes

1

How old is Mrs. Montes going to be?

30

2

How many kids does Mrs. Montes have? 

2 

3

How many cats does Mrs. Montes have? 

3 cats

4

How many years has Mrs. Montes been teaching at Carver? 

This is my 5th year

5

What grade did Mrs. Montes teach before coming to Carver to teach 6th grade?

1st grade

Triangles

1

How many degrees are in a triangle? 

180 

2

What is the area formula for a triangle?

A=1/2bh

3

What is the missing angle of a right triangle where one angle is 40 degrees?

right triangle=one 90 degree angle

90+40=130

180-130=50

4

Do these sides make a triangle?

42, 81, 39

NO! 

The sum of the 2 shortest sides must be GREATER than the 3rd side.

Remember, if the sum is NOT greater, the roof will collapse!

5

What is the area of a triangle that has a bottom of 30inches, 15 inches tall, and a side length of 12inches?

A=1/2bh
=1/2(30)(15)
=1/2(450)
A=225

Trapezoids

1

What "shortcut" do we use to call the side lengths of trapezoids or triangles?

Michael Jackson (MJ)

teheeeee

2

You can tell which sides are the bases of the trapezoids because they are _________ of each other. 

*hint: I had yall use your arms to show me what that word meant. 

Parallel

3

What is the formula for a trapezoid?

A=1/2(b1+b2)h

4

Solve the area of a trapezoid if the base is 2 and 5, and the height is 6

A=1/2(b1+b2)h
=1/2(2+5)(6)
=1/2(7)(6)
=1/2(42)
A=21

5

Solve for the area of the trapezoid that has side lengths of 6, a top base of 3, bottom base of 8, and a height of 4. 

A=1/2(b1+b2)h

=1/2(3+8)(4)
=1/2(11)(4)
=1/2(44)
A=22
