A candy bar box is in the shape of a triangular prism. The volume of the box is 3,240 cubic centimeters. A triangular prism is shown with base of triangle labeled 24 cm, sides of the triangle labeled 15 cm, and length of the box equal to 30 cm.

Part A: What is the height of the base? Show your work. (5 points)

Part B: What is the approximate amount of cardboard used to make the candy box? Explain how you got your answer. (5 points)

I only need part B of this question, thanks for your help :D

Part A = 9

Part B = 1,836 cm2

Step-by-step explanation:

Part A

V = (A)(h)

3240 = (1/2)(24)(h)(30)

3240 = (12)(h)(30)

3240 = 360(h)

h = 3240/360

h = 9

Part B

Area of both Triangle:

2(1/2) (24)(9) = 216cm2

Total area of 24cm x 30cm rectangle:

(24)(30) = 720 cm2

Total area of two 30cm x 15cm rectangles :

(2)(30)(15) = 900cm2

Total amount of cardboard to make candy box is:

216cm2 + 720 cm2 + 900cm2 = 1,836cm2

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

1696 hundred thousand
