width: 4 inches

height: 8 inches

Havana has a shipping box similar to Jake's box, but each dimension is half as long.

How many times larger is the volume of the Jake's box than Havana's box?

Respuesta :

Answer:

(1)750 cubic feet

(2)8 Times

Step-by-step explanation:

Question 1

Dimensions of the Right Triangular Base

  • Base = 20 feet
  • Height= 120 inches = 10 feet

Base Area of the Prism

[tex]=\dfrac12 \times 20 \times 10\\=150$ square feet[/tex]

  • Height of the Prism = 5 feet

Volume of the Prism = Base Area X Height

= 150 X 5

=750 cubic feet

Question 2

Jake's Box

  • Length: 12 inches
  • Width: 4 inches
  • Height: 8 inches

Volume = 12 X 4 X 8 =384 cubic inches

Havana's box

Havana has a shipping box similar to Jake's box, but each dimension is half as long.

Therefore:

  • Length: 12/2=6 inches
  • Width: 4/2=2 inches
  • Height: 8/2=4 inches

Volume = 6 X 2 X 4 =48 cubic inches

Now:

384/48=8

Therefore, the volume of Jake's box is 8 times larger than Havana's box.
