1. Fact or Fib
7.9A & 7.9D

2. Instructions:
1) As a group review the information given about each shape.
2) A statement will be made about the shape.
3) Determine with your group if the statement is a FACT or a FIB.
4) If it is a FIB, what would be a FACT statement that could be made instead.

3. FACT or FIB?
V=Bh
V= (5*4)x 6
V= 20 x 6
Fact
V= 120 cm³
Fact.

4. FACT or FIB?
To determine the volume of this triangular prism, you would use 44cm as B.
Fib!
FIB. B is the area of the base, the base is the triangle rather than the rectangle. B=6
Students would need to tell you the correct number for big B and then they could solve for the volume.

5. Fib! FACT or FIB? V= Bh V= (8*7) x 6 V= 336 in³
Fib. Students should note that the wrong formula for volume of a rectangular pyramid was used. 112in cubed is the correct volume

6. Fib! 511.89 cm³ FACT or FIB? Solve
To find the volume of the triangular pyramid you would use 18.9 as b for the triangle?
Solve
Determine the Volume of the triangular pyramid.
Fib is not needed to determine the volume of the triangular pyramid
cm³

7. Fact
All three of the rectangular prisms have the same volume?
Fact

8. Fib! Jason solved for the volume of this triangular prism correctly.
Fib. He used the hypotenuse of the triangle as the height of the prism.

9. Allison built a rectangular prism toy box.
Fib!
The dimensions of the base of this toy box are 12 inches by 24 inches.
FIB. The base dimensions are 24 x 36
The toy box has a volume of 9ft³.
The height of the toy box is 18inches.

10. Fact The height of the pyramid is 6 inches.
The volume of this pyramid is 12in³.
