Answer:
1. The figure formed are pyramids with rectangular base. The figure B is the same that figure C, and the figure D is the same that figure E.
2. Jerremy's puzzle form a rectangular prism with rectangular base of 6 units x 8 units and height of 10 units. The volume of the prism is 480 units^3.
3. The sum of the volume of the five figures (combined volume) is equal to the volume of the rectangular that they form when we fit them together.
Step-by-step explanation:
1. The figure formed are pyramids (see the first attached file).
A: Pyramid with rectangular base 6 units x 8 units
B: Pyramid with rectangular base 6 units x 10 units and height 4 units
C: Pyramid with rectangular base 6 units x 10 units and height 4 units
D: Pyramid with rectangular base 8 units x 10 units and height 3 units
E: Pyramid with rectangular base 8 units x 10 units and height 4 units
The figure B is the same that figure C, and the figure D is the same that figure E.
2. Jerremy's puzzle form a rectangular prism (see the second attached file) with rectangular base of 6 units x 8 units and height of 10 units.
Width: w=6 units
Length: l=8 units
Height: h=10 units
Volume of the prism: V=Ab*h
Area of the base: Ab=w*l→Ab=(6 units)*(8 units)→Ab=48 units^2
V=Ab*h→V=(48 units^2)*(10 units)→V=480 units^3
3. The sum of the volume of the five figures (combined volume) is equal to the volume of the rectangular that they form when we fit them together.
