Answer 1

Answer:(B) 85 degrees

Explanation:

Answer 2

(1)750 cubic feet

(2)8 Times

Explanation:

Question 1

Dimensions of the Right Triangular Base

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

Base Area of the Prism

`=\frac12 * 20 * 10\\=150$ square feet`

• 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.
