1. the answer part 6) is

   5.12 cm³

   Step-by-step explanation:

   I chose a box of cereal> rectangular prism

   see the attached figure

   Part 1)List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).

   Length: 20 cm

   Width: 8 cm

   Height: 32 cm

   Part 2).

   Describe the shape of the cross-section when the box is cut parallel to the base

   the shape of the cross-section would be a rectangle of dimensions

   20 cm x 8 cm

   Part 3)

   What is the surface area of the box?  

   surface area=2*area of the base + perimeter of the base*height

   area of the base=20*8=160 cm²

   perimeter of the base=2*[20+8]> 56 cm

   height=32 cm

   surface area=2*160+56*32> 2,112 cm²

   the answer part 3) is

   2,112 cm²

   Part 4)

   What is the surface area of the box if it is scaled up by a factor of 10?

   we know that

   surface area of the larger box=[scale factor]²*surface area original box

   scale factor=10

   surface area original box=2,112 cm²

   so

   surface area of the larger box=10²*2,112> 211,200 cm²

   the answer part 4) is

   211,200 cm²

   Part 5)  

   What is the volume of the box?

   volume of the box=L*W*H> 20*8*32> 5,120 cm³

   the answer Part 5) is

   5,120 cm³

   Part 6)  

   What is the volume of the box if it is scaled down by a factor of 1/10

   we know that

   volume of the smaller box=[scale factor]³*volume original box

   scale factor=1/10

   volume original box=5,120 cm³

   so

   volume of the smaller box=[1/10]³*5,120> 5.12 cm³

   the answer part 6) is

   5.12 cm³

   3. the surface area is 2,112 cm²

   4. 211,200 cm²

   5. 5,120 cm³

   6. 5.12 cm³

2. Option B.

   Explanation:

   Δ STEPS TO SOLVE Δ

   ║$325 budget

   ║Price → $8 per T-shirt + $45 delivery charge

   ║8x + 45 = 325

   ║x = 35

     ⇒ With $325, you can purchase 35 T-shirts or less.

   Option A is incorrect, because the point starts at 45 T-shirts and decreases.Option B is correct, because the point starts at 35 T-shirts and decreases.Option C is incorrect, because the point starts at 45 T-shirts and increases.Option D is incorrect, because the point starts at 40 T-shirts and increases.

                          [ Therefore, your answer should be option B. ]
